Makes sense I think.

Note that it doesn't make PostgreSQL upgrades work, e.g. if you switch
from jessie to stretch, it won't automatically pull in
postgresql-9.6-pgsphere if you had postgresql-9.4-pgsphere installed
before, as both provide postgresql-pgsphere. We'd need real meta
packages for that, but that would mean even more .debs, which I'd be
reluctant to add.
