So we can say that we can upgrade, at least in theory, but that's not the
official policy?

FWIW, that's pretty tame compared to trying to migrate and upgrade an
Oracle database. Have you ever seen some of the upgrade path rules for
Oracle? If it's this version, first migrate to this version and then
upgrade, but if it's this other version, then it can upgrade directly,
unless it's the beta version, then you have to migrate blah blah blah...
Is it feasible to create a 'universal installer' for PostgreSQL similar to
what Oracle has (especially for binary distributions) that will do the
data migration behind the scenes? Doing the source compile will probably
require migrating the stuff manually (but if you are installing from
source, you are doing everything manually *anyway*).
