I just realized that myself. The code was still doing it the hard
way (eg, logging *both* before and after events for each tuple),
but it does seem necessary to log all events if there is either an
UPDATE or DELETE deferred trigger.

I suspect it just masks the problem by preventing the trigger code
from executing ...
