alsoorthogonal to the purpose of this patch.  The only sense in which this patch depends on that issue is that this
patchproposes that non-superuser subscription owners are already an issue, and therefore that this patch isn't creating
anew 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.
