If recovery.conf has this configuration parameter:
primary_slot_name = repmgr_slot_1
The replication use replication slots otherwise when wal_keep_segments is reached, the redo logs are rotated.
With replication slot you only have the required wal files but with wal_keep_segments you only has the amount especified in it.
If you do not use replication slots there is no need of creating slots, see SELECT * from pg_replication_slots; on the master.
When a slot is used, wal_keep_segments has no effects and could be 0.

Asunto: Re: [ADMIN] Big sized materialized views break replication
Is it possible to use replication with slots and without them in the same setup or it could cause a problem?
