Probably I am on the wrong place but for me NULL on numbers means 0 or ZERO.
I know about standards...


You can easily convert NULLs to 0 in your queries - read about COALESCE function http://www.postgresql.org/docs/8.0/interactive/functions-conditional.html. Compare these SELECTs:

CREATE TABLE test (num INTEGER);
INSERT INTO test VALUES (1), (2), (null), (3), (null), (4), (0);

SELECT num FROM test;

SELECT COALESCE(num, 0) FROM test;


but I think that integralism is somewhat wrong.
