If archiving has stalled, it's not a clean shutdown anyway and I
wouldn't expect the wal archive to be automatically complete. I'd still
appreciate a warning that while the shutdown appeared regular, wal
wasn't written completely. But the "corner case" of shutting down a
smoothly running server, the wal archive archive should be complete as well.
