Cases with lots of irrelevant indexes. Zoltan's example had 4 indexes per child table, only one of which was relevant to the query. In your test case there are no irrelevant indexes, which is why the runtime didn't change. regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
