Another way is explained in wiki:
$ psql -c "SELECT pg_current_xlog_location()" -h192.168.0.10 (primary host) pg_current_xlog_location -------------------------- 0/2000000 (1 row) $ psql -c "select pg_last_xlog_receive_location()" -h192.168.0.20 (standby host) pg_last_xlog_receive_location ------------------------------- 0/2000000 (1 row) $ psql -c "select pg_last_xlog_replay_location()" -h192.168.0.20 (standby host) pg_last_xlog_replay_location ------------------------------ 0/2000000 (1 row)
