Good for you!
I don't think anybody is trying to deviate from your request, the
point is as described in the documentation of PQftype you have been
already pointed out. And according to me, the approach is flexible
enough to allow for extending the type system without problems.
Last, it is not clear to me what the original problem (getting a
different oid from your libpq example) was generated from: did you
queried the catalog?
