As far as I am concerned that is way too much, particularly considering that your test case isn't designed to be particularly memory-allocation intensive, and if it is up to me I will reject this. Even a quarter-percent slowdown for a feature that will be used only by a small fraction of users only a small fraction of time time seems totally unacceptable to me. ...Robert -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
