How to do it…

  1. Set max_replication_slots > 0 on each sending node. This change requires a restart. Set the value to at least one more than the number of planned slots:
max_replication_slots = 2
  1. For PSR slots, you have to first create the slot on the sending node, like this:
SELECT (pg_create_physical_replication_slot('alpha_beta_1', true)).wal_position;wal_position----------------- 0/5000060
  1. Monitor it in use by using the following:
SELECT * FROM pg_replication_slots;
  1. In the recovery.conf file in the data directory on the standby, set the primary_slot_name parameter using the unique name that you assigned earlier:
primary_slot_name = 'alpha_beta_1'

Slots can be removed using the following query:

SELECT pg_drop_physical_replication_slot('alpha_beta_1'); ...
