I understand and agree.
Anyway, we suggest our customers to use sequences instead of serials.

It’s Informix that you should be complaining about. Zero is not a sane value to specify special behaviour, it could mean zero and be just as valid. By consequence, Informix probably forbids zero as a sequence value, but that is an artefact (and a limitation) of its implementation, not a feature. The core of your problem however, is that you’re trying to get database-agnostic behaviour by relying on database-specific features. That is not going to work, you’ve just been lucky enough to get away with it until now. There’s really only one realistic answer here: Fix your design.
