(a) How would JDBC know what to do better than the backend does?
What happens when (not if) JDBC puts out an inappropriate coercion?

(b) This is an acknowledged shortcoming that will be fixed someday.
I don't think it's appropriate to try to put temporary band-aids for
backend shortcomings in frontend drivers. Surely the folks working on
JDBC have their own set of shortcomings to work on...
