OK, here is a cleaned up version of the patch that will apply to current
CVS. I worked it into the SO_PEERCRED code. I made some changes so it
compiles on BSD/OS. I am getting "Invalid Argument" from libpq's
sending of the credentials on BSD/OS. I would be interested to know if
this works on FreeBSD. Solaris uses this capability too.

Also, we are not updating the protocol version, so I hope it fails
gracefully on old clients.
