I'm not convinced this is an improvement; it's just one more value to confuse people with. And any implementation of quicksort is likely to have a fast exit path for 0 or 1 item, so I don't think the existing display is incorrect either. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
