psql has supported older servers for a great while now, so this sort of things seems pretty useless now:
psql (9.2rc1, server 9.1.4) WARNING: psql version 9.2, server version 9.1. Some psql features might not work I think it should be reduced to warning when connected to a newer server. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
