How does 7.1 work now with the vacuum and all?

Does it go for indexes by default, even when i haven't run a vacuum at all?
Does vacuum lock up postgres? It says the analyze part shouldn't, but how's
that for all of the vacuum?

An 7.0.3 db we have here we are forced to run vacuum every hour to get an
acceptable speed, and while doing that vacuum (5-10 minutes) it totaly
blocks our application that's mucking with the db.

Instead of asking why a piece of software is using "1970s technology,"
start asking why software is ignoring 30 years of accumulated wisdom.

What's the deal with vacuum lazy in 7.1? I was looking forward to it. It was
never clear whether or not you guys decided to put it in.

If it is in as a feature, how does one use it?
If it is a patch, how does one get it?
If it is neither a patch nor an existing feature, has development stopped?

If you actually download and read the enclosed READMEs it's pretty
clear.

I have no idea, I haven't been tracking postgresql all that much
since leaving the place where we contracted that work.

Vadim never got to merging into the 7.1 tree.

I still had no time to port it to 7.1 -:(
I'll post message to -hackers when it will be ready.
