There are known bugs in 8.4.0 having to do with improperly exchanging the ordering of semijoins (IN joins) and other joins. You haven't provided enough information to test whether your case is one of them. If you can try CVS branch tip or a recent nightly snapshot, there might still be enough time to do something about it for 8.4.1, if it isn't fixed already. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
