Howdy. I seem to have inherited this problem: http://www.postgresql.org/message-id/EF524E81-B815-4122-A337-7E50BCED514E@xxxxxxxxxxxxxxx Basically a subselect with no offset is resulting in really poor performance with 120s queries but adding an offset 0 to the inner sub select results in 0.5s query times, and I get the same output. The original answer Robert Haas asks for a self contained test case. I am running 8.4.15 and can try 8.4.17 if some patch has been applied to it to address this issue. I just want to know should I A: upgrade to 8.4.17 or B: create a self contained test case. -- To understand recursion, one must first understand recursion. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
