I'd like to know more about the reasoning here. This thread started out
by suggesting a new special role that can be used for subscriptions,
but now it's changing the way subscription happens.
* What are the most important use cases here? Are we just trying to
avoid the unnecessary use of superuser, or is there a real use case for
subscribing to a subset of a publication?
* What are all the reasons CREATE SUBSCRIPTION currently requires
superuser?
* Is the original idea of a special role still viable?
