Do i need streaming replication slots as many of replicas in postgres? Correct me if I am wrong but I’m thinking that if I have 4 different read only replica servers I need 4 streaming replication slots, one for each of them?
Or all of them can you use one?
Each replication slot requires a unique primary_slot_name in the recovery.conf, so you will need to have 4 connections for a streaming replication slot.
