There are lots of surprising things in SQL. And *of course* the only complaints come from people who didn't know about it, not from satisfied users. The reason people don't know about this feature is that it's so poorly documented --- there's just one mention buried deep in chapter 35 of the manual, in a place where most people wouldn't think to look for it. I'm not quite sure where's a better place though. 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
