continuing with the postgres replication using WARM STANDBY, what happens to the wal_files which keeps on generating on the primary?
Do we have to manually remove them or they are removed automatically, once they have been recovered on the warm standby?
Also a quick question, do we have to have a NFS for the wal_files, which will be mounted on both the servers, or we can have folders on each server and configure DRBD between them, so that whatever happens on one is copied automatically on to the other.
Thanks!

simply checks to see if the file exists, and if it does, the recovery
loop is stopped.
