[COMMITTERS] pgsql: Teach RemoveRoleFromObjectPolicy() about partitioned tables.

Teach RemoveRoleFromObjectPolicy() about partitioned tables.

Table partitioning, introduced in commit f0e44751d7, added a new
relkind - RELKIND_PARTITIONED_TABLE. Update
RemoveRoleFromObjectPolicy() to handle it, otherwise DROP OWNED BY
will fail if the role has any RLS policies referring to partitioned
tables.
