I was just about to submit this suggestion. We do the same on Gentoo, as a
default anyway. (Users can pick their own locations for the configuration files
and data directories.) It would simplify the upgrade process by eliminating two
to four steps. (Symlink/copy configuration files in /etc/postgresql-${SLOT}
to /var/lib/postgresql-${SLOT}, same to $version++, pg_upgrade, remove symlinks.)
