Okay, that answers one of my questions, thanks Andrew. Is this something
that others may be interested in? Is it realistic to ask that it be added
to the TODO list?
What kind of writes occur normally, how does file locking work. Could you
direct me to other resources on this for postgresql?

Yes, both good ideas, we've been kicking these around. But we just wanted
to exhaust the possibilities before we "give in" :)

One more idea, is it possible to "fake" a read-write file system. I.e.
supply the files that postgresql will be looking for? (I know it's a
stretch, but hey, this IS the "hackers" list) :)

Thanks guys.
