One of the problems I was experiencing was one of my recovery databases
disk was filling up, I solved this by using pg_archivecleanup
The real cause of this appears to be that overnight my database produces
something on the order of 1200 to 2500 WAL archives which are being
transmitted correctly to the replication databases, but they are having
trouble replaying these logs fast enough to ever get caught up.
archive_timeout is not set, but I believe the default is 0
Is this likely that the disks are too slow on the replication servers,
or is something else happening, such as the restoration of logs is
considerably slower than on the primary?
