psql should work the same, apart from new metacommands. I don't think you'll experience issues with pg_ctl. I would not recommend you to user pg_dump and pg_restore. They are pretty sensitive to the PostgreSQL release. -- Guillaume http://www.postgresql.fr http://dalibo.com -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
