True. But even though the server is running normally, the misconfiguration
might still make PQping return PQPING_NO_ATTEMPT and make pg_ctl -w
fail to wait for complete startup. Currently misconfiguration of password
authentication doesn't interfere with pg_ctl -w, so we can remove the
reference to that. But other misconfigurations can be still harm, so I thought
the sentence still needs to be in the document.
