I have slept on it, and while this is a nice idea, I think your
suggestion that this would take about the same effort as what I had in
mind (which I could just about have coded by now) is out by at least an
order of magnitude. I think it would eat up all my available time
between now and Nov 15, and I'm not prepared to spend my time budget
that way.

I will talk to the requestor and see if we can do something along the
lines of Robert's suggestion using a plperlu function and a temp file,
which I think I could do within the original time budget.

Consider the suggestion withdrawn.

cheers
