the last time i talk with Bernd Helmle, he was preparing the code to
send to patches for discussion... that was two months ago...
the current code had problems with casts and i think with domains too...
i will contact with Bernd to know if he did some more work, if not i
can send to patches the latest path he sent me...

I'd certainly be interested in having auto-updatable views in 8.2 - even
if it was only for the simplest of cases. If I can be of any help
testing etc. let me know.

Yeah, that would be cool. I've sent the latest patch to -hackers. Feel free
to check it out. I currently know that array fields (e.g. field[1]) causes
problems, but i'm pretty sure there's much more work left...
