I'll change the patch as above. Done. But there is one issue; the extra search is always required to send a notify interrupt. This is because pg_listener doesn't have a backend ID and we cannot pass it to SendProcSignal. In order to solve this issue, we should newly add backend ID field into pg_listener?
