I have two 9.2 databases running with hot_standby replication. Today when I was checking, I found that replication has not been working since Mar 1st.
There was a large database restored in master on that day and I believe after that the lag went higher.
SELECT pg_xlog_location_diff(pg_current_xlog_location(), '0/0') AS offset
431326108320
SELECT pg_xlog_location_diff(pg_last_xlog_receive_location(), '0/0') AS receive, pg_xlog_location_diff(pg_last_xlog_replay_location(), '0/0') AS replay
receive | replay

I checked the pg_xlog in both the server. In Slave the last xlog file
-rw------- 1 postgres postgres 16777216 Mar 1 06:02 00000001000000390000007F
In Master, the first xlog file is
-rw------- 1 postgres postgres 16777216 Mar 1 04:45 00000001000000390000005E
Is there any way I could sync the slave in quick process?
Thanks.
