Use UNC paths, that is \\SERVER\SHARE\DIR\FILE. This will require a
domain user - there is no way around that, other than setting up an
anonymous share (and you shouldn't do that :P).

Your other option is to log in manuallty as the postgres account (with
the service *stopped*, this si important). Map the drives with
persistance. Then log off, *then' start the service. That should work,
but I would personally never rely on that for a production system.

That said, I'm also not sure I'd trust postgresql running over a Windows
share. In theory it should work fine, but I'm not certain enough on how
things like fsync() are handled over those. Perhaps someone else can say
something about that.
