If you have a better idea, we can discuss it, but to some degree I think that is also orthogonal to the purpose of this patch. The only sense in which this patch depends on that issue is that this patch proposes that non-superuser subscription owners are already an issue, and therefore that this patch isn't creating a new issue, but rather making more sane something that already can happen.

Don't we want to close this gap irrespective of the other part of the
feature? I mean if we take out the part of your 0003 patch that checks
whether the current user has permission to perform a particular
operation on the target table then the gap related to the owner losing
superuser privileges should be addressed.
