The regression tests are in src/interfaces/libpq/test
and currently contain only URL parsing tests.

I suggested exactly that here:
http://www.postgresql.org/message-id/D960CB61B694CF459DCFB4B0128514C208A4EDD4@exadv11.host.magwien.gv.at
and met resistance:
- one can use libpqtypes
- I couldn't find a convincing use case
- it clutters up the API

I think that you'll need to explain in more detail why
your proposed additions would be necessary for your project.
Especially since many good drivers have been written against
libpq as it is.
