To be more enlighting (at least a bit):

I haven't had the postgreSQL sources handy so I first poked a bit
around.  Then I downloaded these sources and found that the affected
postgreSQL function StreamConnection() accepts a connection.  This
was the hint I missed.  My change to return a correct path for AF_LOCAL
sockets in a call to getsockname() requires calling a fhandler_socket
method set_sun_path().  I called it in cygwin_bind() but I forgot to
call it for the newly created socket in a call to cygwin_accept.

I hope that fixes it.
