Slots are *exactly* the mechanism that enables multiple versions of the
same package to be installed in parallel and it works fantastically well.
However since not every package is easily slottable (such as the old and
therefore unslotted postgres 8.1.x) it is not an option in Andrus' case,
and also wouldn't solve the problem of upgrading the DB itself, which is
purely a PostgreSQL problem on any platform.

And FYI Gentoo supports binary packages just fine; in fact that's how you
are supposed to install packages on larger installations.
