Hmm - well, you're explicitly telling it to insert VALUES (..., new.field3,
...) so if new.field3 is null then it *should* do that.

Now - how you should go about getting the default I don't know. You could
build a rule with WHERE NEW.field3 IS NULL and then not pass field3, but that
would stop you explicitly setting it to null.

Out of curiosity, can you tell me what happens if you insert into the view
('C',DEFAULT,DEFAULT)?
