What would be less confusing?
I think it's similar enough to how Debian handles library upgrades.

postgis
Use case: you installed postgis-2.2, created the extension, set it up to
be used in a database, and later do an 'apt-get dist-upgrade', giving
you postgis-2.3. Your database will continue to work (with the
postgis-2.2 version).
Upgrading PostgreSQL is an entirely different story.
