Win32 question: getppid() with no parent?

[Tom Lane <tgl(at)sss(dot)pgh(dot)pa(dot)us>]

On Unix, it is possible to tell whether your parent process has died
by checking to see if you have become a child of init:

	if (getppid() == 1)
	   /* oh dear, I am an orphan */

Is there equivalent functionality available on Windows?

Currently, we have the pgstat child process checking for postmaster
death by watching for read-ready on a pipe.  This does not scale
pleasantly to multiple long-lived postmaster children, though, so
I'm wondering about ways for the children to detect a postmaster crash
without requiring any direct postmaster cooperation.
