For the particular case Robert is proposing, the *header* isn't a
problem, because the only types it would deal in are Oid, bool,
const char *, and List *.  But you're right that in general this design
pattern carries a risk of having to include the world in a commonly-used
header file, which is certainly not a good idea.
