Yeah. I've dropped the idea personally -- the suggestion that the table
owner can provide a SECURITY DEFINER procedure to do the TRUNCATE if he
wants to allow others to do it seems to me to cover the problem.

I don't think we should put weird special cases in the rights checking
to allow this -- that's usually a recipe for introducing unintended
security holes.
