PostGIS uses unpackaged-to-XXX pretty heavily, and has it under
automated testing (which broke since "FROM unpackaged" support was
removed, see 14514(dot)1581638958(at)sss(dot)pgh(dot)pa(dot)us)

We'd be ok with requiring SUPERUSER for doing that, since that's
what is currently required so nothing would change for us.

Instead, dropping UPGRADE..FROM completely puts us in trouble of
having to find another way to "package" postgis objects.
