How about this?
ALTER TABLE blah ALTER COLUMN col UNSET NOT NULL;
I would almost think that it should be NOTNULL anyway to make it clear that we
are setting (or unsetting) one thing and that it is not a weird way of saying
"...NOT SET NULL" or "NOT UNSET NULL" but I realize that it should also look
more like the NOT NULL clause we already have in the CREATE TABLE query.
