Depending on the checkpoint frequency and the activity on your
systems, you may face problems with missing WAL segments at some point
because past WAL segments need to be recycled or removed by the server
to move on with its life. One way to take care of this class of
problems is to use wal_keep_segments. An even better one is called
replication slot. This solely depends on how your system is working,
so perhaps you will not need some extra configuration.
