Thanks.  I meant to surround the Cygwin specific stuff with a case
statement but forgot -- thanks for cleaning up after me.  Sigh...

See attached patch and ChangeLog.  This trivial patch enables UNIX
domain sockets for Cygwin.  This version of Cygwin PostgreSQL still
passes all regression tests.  However, there are two issues with
Cygwin's support of UNIX domain sockets:

    1. psql (and other clients) with hang if postmaster is not running
       and the socket file (e.g., /tmp/.s.PGSQL.5432) exists
    2. Cygwin's AF_UNIX sockets are really implemented as AF_INET
    sockets so they are inherently insecure.  See the follow for more
    details:

       http://sources.redhat.com/ml/cygwin/2000-12/msg01058.html

The procedure to apply the patch is as follows:

    $ cd pgsql
    $ # save attached patch to current directory
    $ patch -p0 <af_unix.patch

Thanks,
Jason
