IIRC, even while HANDLE is a 64-bit value on Win64, only the lower

Good.
I think all we need here is a way to shut up the overly-anal-retentive
warning. I would have expected that explicit cast to be enough,
actually, but apparently it's not. Ideas?
Not sure about that one. Certainly seems like that case should be
enough - it always was enough to silence similar warnings on MSVC in
the past...
If we cast the HANDLE to a long long first and then truncate it the
compiler is silent, it only complains if that's done in one operation.
So maybe something like:
#ifdef WIN64
#define ULONGPID(x) (unsigned long) (unsigned long long) (x)
#else
#define ULONGPID(x) (unsigned long) (x)
#endif
...
printf(_("running on port %d with pid %lu\n"),
port, ULONGPID(postmaster_pid));
It's a bit ugly, but we've done worse.
cheers
