Dear Amit, > Can't we use --replication-slot=name to avoid this ERROR? I mean use > different replication slot names.
Are you saying the below case, right? It can work. ``` $ pg_createsubscriber -D data_sta/ -P 'user=postgres port=5432' -d postgres --subscription sub --replication-slot=slot1 -d testdb --subscription sub --replication-slot=slot2 -U postgres ``` BTW; slot creations are tried before the standby promotes, thus there may be a chance user read the error message, change the subscription name, and retry. But I still think we should guard the combination, which means it's too late for PG19. Best regards, Hayato Kuroda FUJITSU LIMITED
