This portion of Kazuhiro's patch obviates the following patch:

    http://www.cygwin.com/ml/cygwin-patches/2001-q3/msg00024.html

I installed the 2001-Jul-25 snapshot and verified that PostgreSQL
shutdowns cleanly and restarts without manual invention when NT reboots.
And there was much rejoicing by Cygwin PostgreSQL users until...

Although this is most likely unrelated to this patch and caused by
something else in this snapshot, I am seeing the following error messages
when using PostgreSQL:

  23606 [main] postmaster 280 close_handle: closing protected handle void sigproc_init ():552(signal_arrived<0x1C0>)
  76914 [main] postmaster 280 close_handle:  by void fhandler_socket::close_secret_event ():122(secret_event<0x1C0>)
pq_recvbuf: recv() failed: Not owner

I will try to track down the above and provide more details and/or
a patch.  But, I thought it better to report the issue instead of
withholding it until I had a chance to work on it.

Thanks,
Jason
