-1 for backpatching; it's more an improvement than a bug fix. In any case, I think we still need to respond to the point Kevin made about how to tell an idle master from broken replication. Right now, you will get at least a few bytes of data every checkpoint_timeout seconds. If we change this, you won't. I'm inclined to think that the way to deal with that is not to force out useless WAL data, but to add some sort of explicit "I'm alive" heartbeat signal to the walsender/walreceiver protocol. The hard part of that is to figure out how to expose it where you can see it on the slave side --- or do we have a status view that could handle that? regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
