Roland Bock db0295a9d0 Remove tvin ... This was a special feature for a project I was working on long ago. It provided implicit behavior for trivial value (0 or "") which were supposed to be interpreted as NULL. They led to `operator==` potentially being serialized as 'IS NULL'. It makes more sense to introduce explicit helpers, e.g. - equal_or_is_null(col, optional) - not_equal_or_is_not_null(col, optional)		2021-07-11 12:47:13 +02:00
