> If we kill the postmaster on master, we will see two processes keep running.
> pguo      44007      1  0 16:35 ?        00:00:00 postgres: port  5432, master logger process
> pguo      44014      1  0 16:35 ?        00:00:00 postgres: port  5432, WAL Send Server process
> Well, maybe we should exit the "WAL Send Server process" so that the processes on master are all gone via checking PostmasterIsAlive() in its loop code.
> Note in distributed system any process could be killed at any time without any callback, handler etc.
