— When an attempt is made to insert an explicit NULL into an INTEGER
PRIMARY KEY column, automatically convert the NULL value into a unique
integer key. This was already happening when an implied NULL was
inserted - when the INTEGER PRIMARY KEY column was omitted from the
list of columns being inserted. Patches from Christian Werner. (CVS 510)
