Re: Does PostgreSQL Stores its database in multiple disks?

You'd be about as well off, if you're running Linux, to use the "md"
RAID driver that simulates RAID in software.

Nobody should be considering using 8.0 for anything called "production
use" at this point in time, because it is NOT guaranteed that there
will be an upgrade path to the "official" release.

Now, I'm possibly 'somewhat conservative,' as someone that wouldn't
want to call a system 'production' if it's using cheapo IDE drives.

But what you're proposing isn't merely a matter of 'trying to jump the
learning curve;' you're tempting, instead, the "learning cliff," and
the results of problems, there, are that instead of scuffing your
knees, you wind up falling 8 stories and going "splat."
