Cool :)

 From http://umitanuki.net/pgsql/wfv08/design.html I got the impression that
windowing functions will make into (at least partially) into 8.4 because on that
page several items are marked with [DONE].

I can't see anything in the developer docs regarding them. Does that mean they
won't make it or that simply the documentation isnt't yet there?

Cheers
