Yes. I believe that the question of having INSERT INTO [tab] check
for permissions is a separate issue from this patch. This patch does
bring the question of whether it *should* check such permission into
more focus, though. Whether it should is probably a matter for a
separate thread, though. I could create arguments in both directions.

This one's fixed in the attached patch, although subsequent events, as
in
=# CREATE TRIGGER trg BEFORE INSERT OR [tab]
are not.
Thanks for your review :)
Cheers,
David.
