If you're sure it's all right, I have a trivial question.

Which signal should we use for the notification to the backend from
WAL sender? The notable signals are already used.

Or, since a backend don't need to wait on select() unlike WAL sender,
ISTM that it's not so inconvenient to use a semaphore for that notification.

Your thought?
