Do i need streaming replication slots as many of replicas in postgres?

Question

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?

Answer 1

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.
