By "last patch" you mean http://archives.postgresql.org/pgsql-committers/2007-10/msg00409.php ? If so that's about as fast as it's likely to get. 22 tables is well beyond what I'd consider reasonable to run through the exhaustive planner. You should try geqo again. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
