Actually, what it's doing is inserting the DEFAULT value for the field
in question. If you don't specify a DEFAULT, it assumes null.
# CREATE TABLE test_tbl (a integer, b text DEFAULT 'bbb', c text);
# INSERT INTO test_tbl (a) VALUES (1);
# SELECT * FROM test_tbl;
a | b | c
---+-----+---
1 | bbb |
If you specify NOT NULL and don't want to provide a value you'll need to
set a DEFAULT.
