agreed. but adding the magic type information is not a task for the
database driver, imho. your example of data coming froma gui just
reinforce my idea of a protocols-driver layer over the DBAPI and under
the OR mappers or applications.

do such types exists? really, i can't imagine a (postgresql) data type
that can't do the round trip.

ok. i am currently rewriting (finishing, that is) psycopg's type system.
can you please tell me _exactly_ how your ideal type-system should work?
i will be glad to give it a try if it is clearly better than current
