Cygwin AF_UNIX socket security improvement patch

The following patch has been recently applied to Cygwin CVS:

    http://www.cygwin.com/ml/cygwin-patches/2001-q2/msg00006.html

I hoping that someone knowledgeable in the area of PostgreSQL sockets
communication can comment on whether or not this will really improve
Cygwin PostgreSQL AF_UNIX socket security.  Recall that Cygwin's AF_UNIX
sockets are really implemented as AF_INET sockets.  Specifically, I'm
interested in whether or not the remaining sendto() and recvfrom() caveats
minimize the effectiveness of this patch with regards to PostgreSQL.

Thanks,
Jason
