getIndexInformationQueryString pulling info from unrelated indexes

[jmdedalus]

The SQL in getIndexInformationQueryString() is missing table join filter.

Currently,

        FROM SYS.ALL_INDEXES ix
          LEFT JOIN SYS.ALL_CONSTRAINTS pc ON ix.INDEX_NAME = pc.INDEX_NAME
          LEFT JOIN SYS.ALL_IND_COLUMNS cols ON ix.INDEX_NAME = cols.INDEX_NAME

...means CONSTRAINT and COLUMN information for any index with the same name across the entire database (ie, all other schemas/owners) is being captured.

In the case of very large databases, this is having the secondary effect of exceeding the 4k character limit on the LISTAGG aggregating function, resulting in the error message ORA-01489: result of string concatenation is too long
