I have a streaming replication running between two servers.
I just upgraded to postgresql 9.3 from 9.2. Earlier on in my 9.2 setup, I have tried that my slave server went offline due to a network outage. This resulted in unshipped wal-log files building up and taking up space VERY fast on my master server.
Can I prevent this in an easy way in 9.3?
I have seen the new wal_sender_timeout config, but I am unsure what exactly it does?
What's the best way of preventing wal-files from building up on sender if receiver goes offline in 9.3?
