[pgAdmin][RM5396] Unable to locate this object in the browser in search objects

Hi Hackers,

Attached is the patch to fix the issues raised in the RM and other issues
which I encountered while fixing. Following are the details:
1) Not able to locate indexes, trigger under partition of partitioned table.
2) Not able to locate columns under catalog schemas other than pg_catalog.
3) Not able to locate foreign keys.
4) Not able to locate rules under a view.
5) Not able to locate user mapping
6) Rules of materialized view and Types from dbms_* packages on EPAS servers
should not be listed in search objects as they are not visible in the
browser tree.

Please review.
