I'm not sure whether we can have a situation where
max_replication_slots < nReplSlotStats i.e. max_replication_slots
getting set to lesser than nReplSlotStats. I think I didn't get the
above mentioned scenario i.e. max_replication_slots == nReplSlotStats
correctly. It will be great if you could throw some light on that
scenario and ensure that it's not possible to reach a situation where
max_replication_slots < nReplSlotStats.
