This is similar but not quite an idea I had: have event triggers owned
by non-superusers run for all non-superusers, but not for superusers.
It is still the case that all non-superusers have to trust everyone with
the event-trigger-create permission, but that's probably the database
owner so most of the time you have to trust them already.
