Well, just the brief look at the docs doesn't immediatly reveal
anything that couldn't be done with straight SQL and server side

Well, that function is several levels below where you need to be
looking. Using it directly will probably get you into a world of hurt.
BTW, what does "alternative server based access to the underlying
