Hi, With PG 17.5 and using logical replication failover slots. When trying to change the value of synchronized_standby_slots, node2 was not running then the error * invalid value for parameter "synchronized_standby_slots": "node1,node2" *was generated. The problem is that statement were affected by this and they can't execute.
