Hello, I would like to be able to add CONSTRAINT and/or DEFAULT with out affecting old rows. Yes, it sounds strange, but... Let's say I have big table, I want to add new column, with DEFAULT and NOT NULL. Normally it means long exclusive lock. So - right now I'm adding plain new column, then DEFAULT, then UPDATE on all rows in chunks, then NOT NULL... Can it be little simpler?
