I have never heard of pg_pause_recovery() or pg_resume_recovery(). However, you can use pg_xlog_replay_pause() and pg_xlog_replay_resume() to pause and resume recovery. As Sameer mentioned, they require the system to be in hot standby mode to use them. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
