Aye, there's at least one more (at least on my development machine).

I wanted to point out that Gentoo does already have a solid way of
handling this -- you just have to use an overlay. If you have "layman"
installed, check out the "postgresql-testing" and
"postgresql-experimental" overlays.

I use the latter and have 8.1.10, 8.2.5 and 8.3beta1 all running happily
on the same machine without having had to do anything other than add
that overlay and set each instance to use a different port. Each release
is very nicely slotted and they all get along just peachy.
