Which pg_upgrade by definition isn't. It is bringing ALL the changes
from one major version to the target version, which may be multiple at
once. Including, but not limited to, catalog schema changes, SQL
language changes, extension behavior changes and utility command
behavior changes.
On that principle, you should advocate against using pg_upgrade in the
first place.
