I looked through this a bit, and the first thing I noticed was it doesn't touch costsize.c at all. That seems pretty wrong; it's little help to have a performance improvement if the planner won't pick the right plan type. There were costsize.c changes in there back in April; what happened to them? 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
