Actually, what c.h does is to provide definitions that are needed in
both frontend and backend code. And we do NOT want to start including
postgres.h in frontend code. It might be that some of the declarations
there are useless to frontend code and could be moved, but trying to be
as strict as you suggest is only going to create problems.
