Not quite.  I think that a non-deferred AFTER trigger would ordinarily
run as the same user that was active when we queued the event, earlier
in the same statement --- but it's possible that some function that
runs in between would change the active role in a non-temporary way.
Doing that will now have different effects than it did before.
