PostgreSQL Installation from Source Code
------------------------------------------------------------------------
This document describes the installation of PostgreSQL using this source
code distribution.
If you are building PostgreSQL for Microsoft Windows, read this document
if you intend to build with MinGW or Cygwin; but if you intend to build
with Microsoft's Visual C++, see the main documentation instead.
------------------------------------------------------------------------
Requirements
In general, a modern Unix-compatible platform should be able to run
PostgreSQL. The platforms that had received specific testing at the time
of release are described in the section called "Supported Platforms"
below.
The following software packages are required for building PostgreSQL:
- GNU make version 3.81 or newer is required; other make programs or
older GNU make versions will *not* work. (GNU make is sometimes
installed under the name "gmake".) To test for GNU make enter:
make --version
- Alternatively, PostgreSQL can be built using Meson. This is
currently experimental and only works when building from a Git
checkout (not from a distribution tarball). If you choose to use
Meson, then you don't need GNU make, but the other requirements
below still apply.
The minimum required version of Meson is 0.54.
- You need an ISO/ANSI C compiler (at least C99-compliant). Recent
versions of GCC are recommended, but PostgreSQL is known to build
using a wide variety of compilers from different vendors.
- tar is required to unpack the source distribution, in addition to
either gzip or bzip2.
- The GNU Readline library is used by default. It allows psql (the
PostgreSQL command line SQL interpreter) to remember each command
you type, and allows you to use arrow keys to recall and edit
previous commands. This is very helpful and is strongly recommended.
If you don't want to use it then you must specify the
"--without-readline" option to "configure". As an alternative, you
can often use the BSD-licensed "libedit" library, originally
developed on NetBSD. The "libedit" library is GNU
Readline-compatible and is used if "libreadline" is not found, or if
"--with-libedit-preferred" is used as an option to "configure". If
you are using a package-based Linux distribution, be aware that you
need both the readline and readline-devel packages, if those are
separate in your distribution.
- The zlib compression library is used by default. If you don't want
to use it then you must specify the "--without-zlib" option to
"configure". Using this option disables support for compressed
archives in pg_dump and pg_restore.
- The ICU library is used by default. If you don't want to use it then
you must specify the "--without-icu" option to "configure". Using
this option disables support for ICU collation features (see the
documentation).
ICU support requires the ICU4C package to be installed. The minimum
required version of ICU4C is currently 4.2.
By default, pkg-config will be used to find the required compilation
options. This is supported for ICU4C version 4.6 and later. For
older versions, or if pkg-config is not available, the variables
ICU_CFLAGS and ICU_LIBS can be specified to "configure", like in
this example:
./configure ... ICU_CFLAGS='-I/some/where/include' ICU_LIBS='-L/some/where/lib -licui18n -licuuc -licudata'
(If ICU4C is in the default search path for the compiler, then you
still need to specify nonempty strings in order to avoid use of
pkg-config, for example, ICU_CFLAGS=' '.)
The following packages are optional. They are not required in the
default configuration, but they are needed when certain build options
are enabled, as explained below:
- To build the server programming language PL/Perl you need a full
Perl installation, including the "libperl" library and the header
files. The minimum required version is Perl 5.14. Since PL/Perl will
be a shared library, the "libperl" library must be a shared library
also on most platforms. This appears to be the default in recent
Perl versions, but it was not in earlier versions, and in any case
it is the choice of whomever installed Perl at your site.
"configure" will fail if building PL/Perl is selected but it cannot
find a shared "libperl". In that case, you will have to rebuild and
install Perl manually to be able to build PL/Perl. During the
configuration process for Perl, request a shared library.
If you intend to make more than incidental use of PL/Perl, you
should ensure that the Perl installation was built with the
usemultiplicity option enabled (perl -V will show whether this is
the case).
- To build the PL/Python server programming language, you need a
Python installation with the header files and the sysconfig module.
The minimum required version is Python 3.2.
Since PL/Python will be a shared library, the "libpython" library
must be a shared library also on most platforms. This is not the
case in a default Python installation built from source, but a
shared library is available in many operating system distributions.
"configure" will fail if building PL/Python is selected but it
cannot find a shared "libpython". That might mean that you either
have to install additional packages or rebuild (part of) your Python
installation to provide this shared library. When building from
source, run Python's configure with the --enable-shared flag.
- To build the PL/Tcl procedural language, you of course need a Tcl
installation. The minimum required version is Tcl 8.4.
- To enable Native Language Support (NLS), that is, the ability to
display a program's messages in a language other than English, you
need an implementation of the Gettext API. Some operating systems
have this built-in (e.g., Linux, NetBSD, Solaris), for other systems
you can download an add-on package from
https://www.gnu.org/software/gettext/. If you are using the Gettext
implementation in the GNU C library, then you will additionally need
the GNU Gettext package for some utility programs. For any of the
other implementations you will not need it.
- You need OpenSSL, if you want to support encrypted client
connections. OpenSSL is also required for random number generation
on platforms that do not have "/dev/urandom" (except Windows). The
minimum required version is 1.0.1.
- You need MIT Kerberos (for GSSAPI), OpenLDAP, and/or PAM, if you
want to support authentication using those services.
- You need LZ4, if you want to support compression of data with that
method; see the configuration parameter default_toast_compression
and the configuration parameter wal_compression.
- You need Zstandard, if you want to support compression of data with
that method; see the configuration parameter wal_compression. The
minimum required version is 1.4.0.
- To build the PostgreSQL documentation, there is a separate set of
requirements; see the main documentation's appendix on
documentation.
If you are building from a Git tree instead of using a released source
package, or if you want to do server development, you also need the
following packages:
- Flex and Bison are needed to build from a Git checkout, or if you
changed the actual scanner and parser definition files. If you need
them, be sure to get Flex 2.5.35 or later and Bison 2.3 or later.
Other lex and yacc programs cannot be used.
- Perl 5.14 or later is needed to build from a Git checkout, or if you
changed the input files for any of the build steps that use Perl
scripts. If building on Windows you will need Perl in any case. Perl
is also required to run some test suites.
If you need to get a GNU package, you can find it at your local GNU
mirror site (see https://www.gnu.org/prep/ftp for a list) or at
ftp://ftp.gnu.org/gnu/.

Installation Procedure
1. Configuration
The first step of the installation procedure is to configure the
source tree for your system and choose the options you would like.
This is done by running the "configure" script. For a default
installation simply enter:
./configure
This script will run a number of tests to determine values for
various system dependent variables and detect any quirks of your
operating system, and finally will create several files in the build
tree to record what it found.
You can also run "configure" in a directory outside the source tree,
and then build there, if you want to keep the build directory
separate from the original source files. This procedure is called a
VPATH build. Here's how:
mkdir build_dir
cd build_dir
/path/to/source/tree/configure [options go here]
make
The default configuration will build the server and utilities, as
well as all client applications and interfaces that require only a C
compiler. All files will be installed under "/usr/local/pgsql" by
default.
You can customize the build and installation process by supplying
one or more command line options to "configure". Typically you would
customize the install location, or the set of optional features that
are built. "configure" has a large number of options, which are
described in the section called "configure Options".
Also, "configure" responds to certain environment variables, as
described in the section called "configure Environment Variables".
These provide additional ways to customize the configuration.
2. Build
To start the build, type either of:
make
make all
(Remember to use GNU make.) The build will take a few minutes
depending on your hardware.
If you want to build everything that can be built, including the
documentation (HTML and man pages), and the additional modules
("contrib"), type instead:
make world
If you want to build everything that can be built, including the
additional modules ("contrib"), but without the documentation, type
instead:
make world-bin
If you want to invoke the build from another makefile rather than
manually, you must unset MAKELEVEL or set it to zero, for instance
like this:
build-postgresql:
$(MAKE) -C postgresql MAKELEVEL=0 all
Failure to do that can lead to strange error messages, typically
about missing header files.
3. Regression Tests
If you want to test the newly built server before you install it,
you can run the regression tests at this point. The regression tests
are a test suite to verify that PostgreSQL runs on your machine in
the way the developers expected it to. Type:
make check
(This won't work as root; do it as an unprivileged user.) See the
file "src/test/regress/README" and the documentation for detailed
information about interpreting the test results. You can repeat this
test at any later time by issuing the same command.
4. Installing the Files
Note:
If you are upgrading an existing system be sure to read the
documentation, which has instructions about upgrading a cluster.
To install PostgreSQL enter:
make install
This will install files into the directories that were specified in
Step 1. Make sure that you have appropriate permissions to write
into that area. Normally you need to do this step as root.
Alternatively, you can create the target directories in advance and
arrange for appropriate permissions to be granted.
To install the documentation (HTML and man pages), enter:
make install-docs
If you built the world above, type instead:
make install-world
This also installs the documentation.
If you built the world without the documentation above, type
instead:
make install-world-bin
You can use make install-strip instead of make install to strip the
executable files and libraries as they are installed. This will save
some space. If you built with debugging support, stripping will
effectively remove the debugging support, so it should only be done
if debugging is no longer needed. install-strip tries to do a
reasonable job saving space, but it does not have perfect knowledge
of how to strip every unneeded byte from an executable file, so if
you want to save all the disk space you possibly can, you will have
to do manual work.
The standard installation provides all the header files needed for
client application development as well as for server-side program
development, such as custom functions or data types written in C.
Client-only installation: If you want to install only the client
applications and interface libraries, then you can use these
commands:
make -C src/bin install
make -C src/include install
make -C src/interfaces install
make -C doc install
"src/bin" has a few binaries for server-only use, but they are
small.
Uninstallation: To undo the installation use the command "make
uninstall". However, this will not remove any created directories.
Cleaning: After the installation you can free disk space by removing
the built files from the source tree with the command "make clean". This
will preserve the files made by the "configure" program, so that you can
rebuild everything with "make" later on. To reset the source tree to the
state in which it was distributed, use "make distclean". If you are
going to build for several platforms within the same source tree you
must do this and re-configure for each platform. (Alternatively, use a
separate build tree for each platform, so that the source tree remains
unmodified.)
If you perform a build and then discover that your "configure" options
were wrong, or if you change anything that "configure" investigates (for
example, software upgrades), then it's a good idea to do "make
distclean" before reconfiguring and rebuilding. Without this, your
changes in configuration choices might not propagate everywhere they
need to.
------------------------------------------------------------------------
configure Options
"configure"'s command line options are explained below. This list is not
exhaustive (use ./configure --help to get one that is). The options not
covered here are meant for advanced use-cases such as cross-compilation,
and are documented in the standard Autoconf documentation.
------------------------------------------------------------------------
Installation Locations
These options control where make install will put the files. The
"--prefix" option is sufficient for most cases. If you have special
needs, you can customize the installation subdirectories with the other
options described in this section. Beware however that changing the
relative locations of the different subdirectories may render the
installation non-relocatable, meaning you won't be able to move it after
installation. (The man and doc locations are not affected by this
restriction.) For relocatable installs, you might want to use the
--disable-rpath option described later.
--prefix=PREFIX
Install all files under the directory "PREFIX" instead of
"/usr/local/pgsql". The actual files will be installed into various
subdirectories; no files will ever be installed directly into the
"PREFIX" directory.
--exec-prefix=EXEC-PREFIX
You can install architecture-dependent files under a different
prefix, "EXEC-PREFIX", than what "PREFIX" was set to. This can be
useful to share architecture-independent files between hosts. If you
omit this, then "EXEC-PREFIX" is set equal to "PREFIX" and both
architecture-dependent and independent files will be installed under
the same tree, which is probably what you want.
--bindir=DIRECTORY
Specifies the directory for executable programs. The default is
"EXEC-PREFIX/bin", which normally means "/usr/local/pgsql/bin".
--sysconfdir=DIRECTORY
Sets the directory for various configuration files, "PREFIX/etc" by
default.
--libdir=DIRECTORY
Sets the location to install libraries and dynamically loadable
modules. The default is "EXEC-PREFIX/lib".
--includedir=DIRECTORY
Sets the directory for installing C and C++ header files. The
default is "PREFIX/include".
--datarootdir=DIRECTORY
Sets the root directory for various types of read-only data files.
This only sets the default for some of the following options. The
default is "PREFIX/share".
--datadir=DIRECTORY
Sets the directory for read-only data files used by the installed
programs. The default is "DATAROOTDIR". Note that this has nothing
to do with where your database files will be placed.
--localedir=DIRECTORY
Sets the directory for installing locale data, in particular message
translation catalog files. The default is "DATAROOTDIR/locale".
--mandir=DIRECTORY
The man pages that come with PostgreSQL will be installed under this
directory, in their respective "manx" subdirectories. The default is
"DATAROOTDIR/man".
--docdir=DIRECTORY
Sets the root directory for installing documentation files, except
"man" pages. This only sets the default for the following options.
The default value for this option is "DATAROOTDIR/doc/postgresql".
--htmldir=DIRECTORY
The HTML-formatted documentation for PostgreSQL will be installed
under this directory. The default is "DATAROOTDIR".
Note:
Care has been taken to make it possible to install PostgreSQL into
shared installation locations (such as "/usr/local/include") without
interfering with the namespace of the rest of the system. First, the
string "/postgresql" is automatically appended to datadir, sysconfdir,
and docdir, unless the fully expanded directory name already contains
the string "postgres" or "pgsql". For example, if you choose
"/usr/local" as prefix, the documentation will be installed in
"/usr/local/doc/postgresql", but if the prefix is "/opt/postgres", then
it will be in "/opt/postgres/doc". The public C header files of the
client interfaces are installed into includedir and are namespace-clean.
The internal header files and the server header files are installed into
private directories under includedir. See the documentation of each
interface for information about how to access its header files. Finally,
a private subdirectory will also be created, if appropriate, under
libdir for dynamically loadable modules.
------------------------------------------------------------------------
PostgreSQL Features
The options described in this section enable building of various
PostgreSQL features that are not built by default. Most of these are
non-default only because they require additional software, as described
in the section called "Requirements".
--enable-nls[=LANGUAGES]
Enables Native Language Support (NLS), that is, the ability to
display a program's messages in a language other than English.
"LANGUAGES" is an optional space-separated list of codes of the
languages that you want supported, for example --enable-nls='de fr'.
(The intersection between your list and the set of actually provided
translations will be computed automatically.) If you do not specify
a list, then all available translations are installed.
To use this option, you will need an implementation of the Gettext
API.
--with-perl
Build the PL/Perl server-side language.
--with-python
Build the PL/Python server-side language.
--with-tcl
Build the PL/Tcl server-side language.
--with-tclconfig=DIRECTORY
Tcl installs the file "tclConfig.sh", which contains configuration
information needed to build modules interfacing to Tcl. This file is
normally found automatically at a well-known location, but if you
want to use a different version of Tcl you can specify the directory
in which to look for "tclConfig.sh".
--with-llvm
Build with support for LLVM based JIT compilation. This requires the
LLVM library to be installed. The minimum required version of LLVM
is currently 3.9.
"llvm-config" will be used to find the required compilation options.
"llvm-config", and then "llvm-config-$major-$minor" for all
supported versions, will be searched for in your PATH. If that would
not yield the desired program, use LLVM_CONFIG to specify a path to
the correct "llvm-config". For example
./configure ... --with-llvm LLVM_CONFIG='/path/to/llvm/bin/llvm-config'
LLVM support requires a compatible "clang" compiler (specified, if
necessary, using the CLANG environment variable), and a working C++
compiler (specified, if necessary, using the CXX environment
variable).
--with-lz4
Build with LZ4 compression support.
--with-zstd
Build with Zstandard compression support.
--with-ssl=LIBRARY
Build with support for SSL (encrypted) connections. The only
"LIBRARY" supported is "openssl". This requires the OpenSSL package
to be installed. "configure" will check for the required header
files and libraries to make sure that your OpenSSL installation is
sufficient before proceeding.
--with-openssl
Obsolete equivalent of --with-ssl=openssl.
--with-gssapi
Build with support for GSSAPI authentication. MIT Kerberos is
required to be installed for GSSAPI. On many systems, the GSSAPI
system (a part of the MIT Kerberos installation) is not installed in
a location that is searched by default (e.g., "/usr/include",
"/usr/lib"), so you must use the options "--with-includes" and
"--with-libraries" in addition to this option. "configure" will
check for the required header files and libraries to make sure that
your GSSAPI installation is sufficient before proceeding.
--with-ldap
Build with LDAP support for authentication and connection parameter
lookup (see the documentation about client authentication and libpq
for more information). On Unix, this requires the OpenLDAP package
to be installed. On Windows, the default WinLDAP library is used.
"configure" will check for the required header files and libraries
to make sure that your OpenLDAP installation is sufficient before
proceeding.
--with-pam
Build with PAM (Pluggable Authentication Modules) support.
--with-bsd-auth
Build with BSD Authentication support. (The BSD Authentication
framework is currently only available on OpenBSD.)
--with-systemd
Build with support for systemd service notifications. This improves
integration if the server is started under systemd but has no impact
otherwise. libsystemd and the associated header files need to be
installed to use this option.
--with-bonjour
Build with support for Bonjour automatic service discovery. This
requires Bonjour support in your operating system. Recommended on
macOS.
--with-uuid=LIBRARY
Build the uuid-ossp module (which provides functions to generate
UUIDs), using the specified UUID library. "LIBRARY" must be one of:
- "bsd" to use the UUID functions found in FreeBSD and some other
BSD-derived systems
- "e2fs" to use the UUID library created by the e2fsprogs project;
this library is present in most Linux systems and in macOS, and
can be obtained for other platforms as well
- "ossp" to use the OSSP UUID library
--with-ossp-uuid
Obsolete equivalent of --with-uuid=ossp.
--with-libxml
Build with libxml2, enabling SQL/XML support. Libxml2 version 2.6.23
or later is required for this feature.
To detect the required compiler and linker options, PostgreSQL will
query "pkg-config", if that is installed and knows about libxml2.
Otherwise the program "xml2-config", which is installed by libxml2,
will be used if it is found. Use of "pkg-config" is preferred,
because it can deal with multi-architecture installations better.
To use a libxml2 installation that is in an unusual location, you
can set "pkg-config"-related environment variables (see its
documentation), or set the environment variable XML2_CONFIG to point
to the "xml2-config" program belonging to the libxml2 installation,
or set the variables XML2_CFLAGS and XML2_LIBS. (If "pkg-config" is
installed, then to override its idea of where libxml2 is you must
either set XML2_CONFIG or set both XML2_CFLAGS and XML2_LIBS to
nonempty strings.)
--with-libxslt
Build with libxslt, enabling the xml2 module to perform XSL
transformations of XML. "--with-libxml" must be specified as well.
------------------------------------------------------------------------
Anti-Features
The options described in this section allow disabling certain PostgreSQL
features that are built by default, but which might need to be turned
off if the required software or system features are not available. Using
these options is not recommended unless really necessary.
--without-icu
Build without support for the ICU library, disabling the use of ICU
collation features.
--without-readline
Prevents use of the Readline library (and libedit as well). This
option disables command-line editing and history in psql.
--with-libedit-preferred
Favors the use of the BSD-licensed libedit library rather than
GPL-licensed Readline. This option is significant only if you have
both libraries installed; the default in that case is to use
Readline.
--without-zlib
Prevents use of the Zlib library. This disables support for
compressed archives in pg_dump and pg_restore.
--disable-spinlocks
Allow the build to succeed even if PostgreSQL has no CPU spinlock
support for the platform. The lack of spinlock support will result
in very poor performance; therefore, this option should only be used
if the build aborts and informs you that the platform lacks spinlock
support. If this option is required to build PostgreSQL on your
platform, please report the problem to the PostgreSQL developers.
--disable-atomics
Disable use of CPU atomic operations. This option does nothing on
platforms that lack such operations. On platforms that do have them,
this will result in poor performance. This option is only useful for
debugging or making performance comparisons.
--disable-thread-safety
Disable the thread-safety of client libraries. This prevents
concurrent threads in libpq and ECPG programs from safely
controlling their private connection handles. Use this only on
platforms with deficient threading support.
------------------------------------------------------------------------
Build Process Details
--with-includes=DIRECTORIES
"DIRECTORIES" is a colon-separated list of directories that will be
added to the list the compiler searches for header files. If you
have optional packages (such as GNU Readline) installed in a
non-standard location, you have to use this option and probably also
the corresponding "--with-libraries" option.
Example: --with-includes=/opt/gnu/include:/usr/sup/include.
--with-libraries=DIRECTORIES
"DIRECTORIES" is a colon-separated list of directories to search for
libraries. You will probably have to use this option (and the
corresponding "--with-includes" option) if you have packages
installed in non-standard locations.
Example: --with-libraries=/opt/gnu/lib:/usr/sup/lib.
--with-system-tzdata=DIRECTORY
PostgreSQL includes its own time zone database, which it requires
for date and time operations. This time zone database is in fact
compatible with the IANA time zone database provided by many
operating systems such as FreeBSD, Linux, and Solaris, so it would
be redundant to install it again. When this option is used, the
system-supplied time zone database in "DIRECTORY" is used instead of
the one included in the PostgreSQL source distribution. "DIRECTORY"
must be specified as an absolute path. "/usr/share/zoneinfo" is a
likely directory on some operating systems. Note that the
installation routine will not detect mismatching or erroneous time
zone data. If you use this option, you are advised to run the
regression tests to verify that the time zone data you have pointed
to works correctly with PostgreSQL.
This option is mainly aimed at binary package distributors who know
their target operating system well. The main advantage of using this
option is that the PostgreSQL package won't need to be upgraded
whenever any of the many local daylight-saving time rules change.
Another advantage is that PostgreSQL can be cross-compiled more
straightforwardly if the time zone database files do not need to be
built during the installation.
--with-extra-version=STRING
Append "STRING" to the PostgreSQL version number. You can use this,
for example, to mark binaries built from unreleased Git snapshots or
containing custom patches with an extra version string, such as a
"git describe" identifier or a distribution package release number.
--disable-rpath
Do not mark PostgreSQL's executables to indicate that they should
search for shared libraries in the installation's library directory
(see "--libdir"). On most platforms, this marking uses an absolute
path to the library directory, so that it will be unhelpful if you
relocate the installation later. However, you will then need to
provide some other way for the executables to find the shared
libraries. Typically this requires configuring the operating
system's dynamic linker to search the library directory; see the
section called "Shared Libraries" for more detail.
------------------------------------------------------------------------
Miscellaneous
It's fairly common, particularly for test builds, to adjust the default
port number with "--with-pgport". The other options in this section are
recommended only for advanced users.
--with-pgport=NUMBER
Set "NUMBER" as the default port number for server and clients. The
default is 5432. The port can always be changed later on, but if you
specify it here then both server and clients will have the same
default compiled in, which can be very convenient. Usually the only
good reason to select a non-default value is if you intend to run
multiple PostgreSQL servers on the same machine.
--with-krb-srvnam=NAME
The default name of the Kerberos service principal used by GSSAPI.
postgres is the default. There's usually no reason to change this
unless you are building for a Windows environment, in which case it
must be set to upper case POSTGRES.
--with-segsize=SEGSIZE
Set the segment size, in gigabytes. Large tables are divided into
multiple operating-system files, each of size equal to the segment
size. This avoids problems with file size limits that exist on many
platforms. The default segment size, 1 gigabyte, is safe on all
supported platforms. If your operating system has "largefile"
support (which most do, nowadays), you can use a larger segment
size. This can be helpful to reduce the number of file descriptors
consumed when working with very large tables. But be careful not to
select a value larger than is supported by your platform and the
file systems you intend to use. Other tools you might wish to use,
such as tar, could also set limits on the usable file size. It is
recommended, though not absolutely required, that this value be a
power of 2. Note that changing this value breaks on-disk database
compatibility, meaning you cannot use "pg_upgrade" to upgrade to a
build with a different segment size.
--with-blocksize=BLOCKSIZE
Set the block size, in kilobytes. This is the unit of storage and
I/O within tables. The default, 8 kilobytes, is suitable for most
situations; but other values may be useful in special cases. The
value must be a power of 2 between 1 and 32 (kilobytes). Note that
changing this value breaks on-disk database compatibility, meaning
you cannot use "pg_upgrade" to upgrade to a build with a different
block size.
--with-wal-blocksize=BLOCKSIZE
Set the WAL block size, in kilobytes. This is the unit of storage
and I/O within the WAL log. The default, 8 kilobytes, is suitable
for most situations; but other values may be useful in special
cases. The value must be a power of 2 between 1 and 64 (kilobytes).
Note that changing this value breaks on-disk database compatibility,
meaning you cannot use "pg_upgrade" to upgrade to a build with a
different WAL block size.
------------------------------------------------------------------------
Developer Options
Most of the options in this section are only of interest for developing
or debugging PostgreSQL. They are not recommended for production builds,
except for "--enable-debug", which can be useful to enable detailed bug
reports in the unlucky event that you encounter a bug. On platforms
supporting DTrace, "--enable-dtrace" may also be reasonable to use in
production.
When building an installation that will be used to develop code inside
the server, it is recommended to use at least the options
"--enable-debug" and "--enable-cassert".
--enable-debug
Compiles all programs and libraries with debugging symbols. This
means that you can run the programs in a debugger to analyze
problems. This enlarges the size of the installed executables
considerably, and on non-GCC compilers it usually also disables
compiler optimization, causing slowdowns. However, having the
symbols available is extremely helpful for dealing with any problems
that might arise. Currently, this option is recommended for
production installations only if you use GCC. But you should always
have it on if you are doing development work or running a beta
version.
--enable-cassert
Enables assertion checks in the server, which test for many "cannot
happen" conditions. This is invaluable for code development
purposes, but the tests can slow down the server significantly.
Also, having the tests turned on won't necessarily enhance the
stability of your server! The assertion checks are not categorized
for severity, and so what might be a relatively harmless bug will
still lead to server restarts if it triggers an assertion failure.
This option is not recommended for production use, but you should
have it on for development work or when running a beta version.
--enable-tap-tests
Enable tests using the Perl TAP tools. This requires a Perl
installation and the Perl module IPC::Run.
--enable-depend
Enables automatic dependency tracking. With this option, the
makefiles are set up so that all affected object files will be
rebuilt when any header file is changed. This is useful if you are
doing development work, but is just wasted overhead if you intend
only to compile once and install. At present, this option only works
with GCC.
--enable-coverage
If using GCC, all programs and libraries are compiled with code
coverage testing instrumentation. When run, they generate files in
the build directory with code coverage metrics. This option is for
use only with GCC and when doing development work.
--enable-profiling
If using GCC, all programs and libraries are compiled so they can be
profiled. On backend exit, a subdirectory will be created that
contains the "gmon.out" file containing profile data. This option is
for use only with GCC and when doing development work.
--enable-dtrace
Compiles PostgreSQL with support for the dynamic tracing tool
DTrace.
To point to the "dtrace" program, the environment variable DTRACE
can be set. This will often be necessary because "dtrace" is
typically installed under "/usr/sbin", which might not be in your
PATH.
Extra command-line options for the "dtrace" program can be specified
in the environment variable DTRACEFLAGS. On Solaris, to include
DTrace support in a 64-bit binary, you must specify
DTRACEFLAGS="-64". For example, using the GCC compiler:
./configure CC='gcc -m64' --enable-dtrace DTRACEFLAGS='-64' ...
Using Sun's compiler:
./configure CC='/opt/SUNWspro/bin/cc -xtarget=native64' --enable-dtrace DTRACEFLAGS='-64' ...
--with-segsize-blocks=SEGSIZE_BLOCKS
Specify the relation segment size in blocks. If both
"--with-segsize" and this option are specified, this option wins.
This option is only for developers, to test segment related code.
------------------------------------------------------------------------
configure Environment Variables
In addition to the ordinary command-line options described above,
"configure" responds to a number of environment variables. You can
specify environment variables on the "configure" command line, for
example:
./configure CC=/opt/bin/gcc CFLAGS='-O2 -pipe'
In this usage an environment variable is little different from a
command-line option. You can also set such variables beforehand:
export CC=/opt/bin/gcc
export CFLAGS='-O2 -pipe'
./configure
This usage can be convenient because many programs' configuration
scripts respond to these variables in similar ways.
The most commonly used of these environment variables are CC and CFLAGS.
If you prefer a C compiler different from the one "configure" picks, you
can set the variable CC to the program of your choice. By default,
"configure" will pick "gcc" if available, else the platform's default
(usually "cc"). Similarly, you can override the default compiler flags
if needed with the CFLAGS variable.
Here is a list of the significant variables that can be set in this
manner:
BISON
Bison program
CC
C compiler
CFLAGS
options to pass to the C compiler
CLANG
path to "clang" program used to process source code for inlining
when compiling with --with-llvm
CPP
C preprocessor
CPPFLAGS
options to pass to the C preprocessor
CXX
C++ compiler
CXXFLAGS
options to pass to the C++ compiler
DTRACE
location of the "dtrace" program
DTRACEFLAGS
options to pass to the "dtrace" program
FLEX
Flex program
LDFLAGS
options to use when linking either executables or shared libraries
LDFLAGS_EX
additional options for linking executables only
LDFLAGS_SL
additional options for linking shared libraries only
