Right.

Linux also has a journaling filesystem available, if you're brave and
wanting to be at the bleeding edge. That's sort of like using next
week's Postgres development sources in yesterday's production environment,
though - a bit risky :)
I should've made it clear that when I was talking about the current,
widespread releases that I'm familiar with. RedHat, in particular.
The RAID stuff is out-of-the-box supported today, fancier stuff
like the journaling file-system will be out-of-the-box supported before
too much longer. It's exciting to see Linux improve steadily just as it's
exciting to see Postgres improve steadily.
