I didn't really care about the former, I was just under the impression
it had to happen first based on some old list posts on the subject.

I dug around in CVS to have a look for this, and I did eventually find
it (well, I found the corresponding docs patch that removed the note
about not working for joins).  I see it's in MAIN but not in
8_1_STABLE.  Does that mean it's headed for 8.2.x when that comes
about? (Sorry, I'm not terribly familiar with how you guys handle all
of this).

Thanks,
