If you can demonstrate that this is not so, I'd like to see it.

This seems to indicate that you may be confused about the difference
between "backend responds with message xyz" and "message xyz will be
immediately delivered to the client". In *all* cases, you should send
either Flush or Sync before waiting for a backend response, because
only those message types force the backend output buffer to be flushed.
