According to mine own research of this problem there are no way to get it. What I would do to monitor the replication lag is 1. execute this on master SELECT txid_current(), that will create a minimal wal entry 2. compare pg_last_xact_replay_timestamp() with current time on replica. assuming that clocks are in sync on both servers of course. -- Sergey Konoplev a database architect, software developer at PostgreSQL-Consulting.com http://www.postgresql-consulting.com Jabber: gray...@gmail.com Skype: gray-hemp Phone: +79160686204 -- Sent via pgsql-admin mailing list (pgsql-admin@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
