Thanks a million. I had actually just found the answer after some
more googling, but I hadn't seen that page and it happens to be

As a side note I'd like to thank everyone here (and especially George,
in this case). I've been on these lists for quite a while and I'm
always amazed at the speed, accuracy and precision of the answers on
the PG mailing lists.
