Default display for NULL should be a zero-length string.That's just as broken as Pavel's suggestion. Unless you have something that is guaranteed distingishable from the output of any non-null value, you really can't make a significant improvement here.
Right. This is the problem we solved in CSV processing by distinguishing between quoted and unquoted values that could be null - the CSV rule is that a null value isn't quoted.
