[COMMITTERS] pgsql: Add partitioned table support to sepgsql

Add partitioned table support to sepgsql

The new partitioned table capability added a new relkind, namely
RELKIND_PARTITIONED_TABLE. Update sepgsql to treat this new relkind
exactly the same way it does RELKIND_RELATION.

In addition, add regression test coverage for partitioned tables.

Issue raised by Stephen Frost and initial patch by Mike Palmiotto.
Review by Tom Lane and Robert Haas, and editorializing by me.
