I'm not hearing anyone speaking against doing this now, so I'm going
to go ahead with it.

While looking this over again, I got worried about the fact that pg_ctl
is #including "miscadmin.h".  That's a pretty low-level backend header
and it wouldn't be surprising at all if somebody tried to put stuff in
it that wouldn't compile frontend-side.  I think we should take the
opportunity, as long as we're touching this stuff, to split the #defines
that describe the contents of postmaster.pid into a separate header file.
Maybe "utils/pidfile.h" ?
