Hi guys, I'm using this query to measure the delay between a Master and a Streaming Replication Slave server, using PostgreSQL 9.2.
SELECT > pg_last_xlog_receive_location() receive, > pg_last_xlog_replay_location() replay, > ( > extract(epoch FROM now()) - > extract(epoch FROM pg_last_xact_replay_timestamp()) > )::int lag; In your opinion, is that right? Cheers Patrick
