I'm using PostgreSQL 9.2.Can you please explain the scenario you are referring to ? during streaming replication ? or during standby promotion ?
Sure...
I've got:
> Master01 (sending wal_files to the slaves)
> slave01 (streaming replication from master01 + wal_files)
> slave02 (streaming replication from master01 + wal_files)
I'll turn slave01 into a master; on recovery.conf:
trigger_file = '/tmp/pg_failover_trigger';touch /tmp/pg_failover_trigger
Then, the new scenario will be:
> slave01 (NEW MASTER)
> slave02 (streaming replication from slave01 + wal_files)
Will slave02 be able to switch the timeline using wal_files provided by the new master?
Thanks
