I didn't hear Stephen propose that "publish" should be a
role-attribute, and I don't understand why that would be a good idea.
Presumably, we don't want unprivileged users to be able to fire up
logical replication because that involves making connections to other
systems from the PostgreSQL operating system user's account, and that
should be a privileged operation. But that's the subscriber side, not
the publisher side.
I don't otherwise follow Stephen's argument. It seems like he's
complaining that PUBLISH might give more access to the relation than
SELECT, but, uh, that's what granting additional privileges does in
general, by definition. Mostly we consider that a feature, not a bug.
