Just to note that I've started looking at this, and I've detected a rather significant omission: there's no check that the join operator has anything to do with the subquery's grouping operator. I think we need to verify that they are members of the same opclass, as relation_has_unique_index_for does. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
