I am still trying to understand this use case. It doesn't feel like
"ownership" to me, it feels more like some kind of delegation.
Is GRANT a better fit here? That would allow more than one user to
REFRESH, or ENABLE/DISABLE the same subscription. It wouldn't allow
RENAME, but I don't see why we'd separate privileges for
CREATE/DROP/RENAME anyway.
This would not address the weirdness of the existing code where a
superuser loses their superuser privileges but still owns a
subscription. But perhaps we can solve that a different way, like just
performing a check when someone loses their superuser privileges that
they don't own any subscriptions.
