Wow, this is great!  It's a pleasure to see capable Cygwin developers

I will resume work on that immediately.

The other problem I've been facing is how to handle the SIGHUP that
Cgywin generates in response to system shutdown.  Some quick tests
show that simply ignoring (SIG_IGN) the signal works, but that defeats
the use of SIGHUP to force the instance to re-read the configuration
file.  It may be, however, that fixing the recv() problem also fixes
the problem where getting a SIGHUP in the midst of stopping PostgreSQL
seemed to mess up the PostgreSQL state.  I'll check...
