No, it is just inconsistency in the documentation. > The create table example for INTEGER contains > “CONSTRAINT INTEG_60” is this a good example?

I know there are cases where string literals can be converted implicitly in dialect 3, but there are also cases where that doesn't work. It looks more like the cases where the implicit conversion works are bugs, strictly speaking.
