I don't think there's any compelling reason for having that log message
in its current form. What about redefining it to mean "postmaster is
ready to accept connections" --- either with that wording, or keeping
the old wording? Then we could just put it in one place in postmaster.c
and be done. I think your proposed patch is overcomplicated by trying
to have it still come out in bootstrap/standalone cases. For a
standalone backend, getting a prompt is what tells you it's ready ;-)
