The problem is that the tool is using the LSN returned by pg_create_logical_replication_slot() as recovery_target_lsn. This LSN is ahead of the current WAL position and the recovery waits until the publisher writes a WAL record to reach the target and ends the recovery. On idle systems, this wait time is unpredictable and could lead to failure in promoting the subscriber. To avoid that, insert a harmless WAL record.
