One query in case of asynchronous replication with replication slots and no
wal archiving if a slave node remains disconnected from master for more
than wal_keep_segments, it will not be able to do the replication when it
comes online.
Now my question is when the slave connects to the master again will the
XLOG in master also keep on building as the slaves replication is stuck or
postgres will remove the replication slot if it is not busy.
