[ For those who missed it ] pg_dump getting things wrong was a big reason to disallow ONLYconstraints. That is pg_dump did not treat ONLY constraints correctly, it always tried to stick them on the parent table: http://archives.postgresql.org/pgsql-bugs/2007-04/msg00026.php I for example had some backups that had to be manually fixed (by removing constraints) to get them to import. I would wager the mentioned clients that have been doing this have broken backups as well :-( Now that we have coninhcnt, conislocal etc... we can probably support ONLY. But I agree with Robert it's probably a bit more than an afternoon to crank out :-) -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
