Cool. Like Robert, no time to review this in detail now, but ...

Assuming that the open pipe descriptor is inherited across exec on
Windows (and if it's not, we're back to square one) all you should
have to do is get the pipe descriptor variables passed down to the
child processes. There's some grotty code in postmaster.c that's
used for this purpose --- see struct BackendParameters and associated
functions. Just add some code there to pass down the values.
I'm not that thrilled with the "life sign" terminology, but don't
have a better idea right offhand.
