FWIW, I don't know of any upgrade procedures for databases that can
quickly do an in-place upgrade when underlying file structures change,
because ultimately you need to read and write the entire database
on-disk. And unless you're going to be real gutsy, you'll also need a
good amount of extra storage somewhere, unless you plan on doing this
in-place upgrade without any backups. And at that point, you almost
might as well just do a dump and reload.

Given that, I don't think setting up a temporary Slony cluster to go
between major versions is that big a deal.
