As mentioned earlier, I'm sick just now and will be back in hospital again tomorrow & monday, so a patch may be a little bit much to ask from me here :-) It's a bit much even keeping up with the posts on the thread so far. I might try to fix the documentation a bit later, though as someone with no experience in marking up volatility on pl/pgsql functions I doubt my efforts would be that great. I also have other OSS project contributions that need some attention first. Re: the google effect. Are these mailing list archives mirrored anywhere, incidentally? For example, I notice we just lost http:reddit.com/r/amd at the weekend, all the discussion of the last few years on that forum is out of reach.
