question about information_schema

I'm trying to implement getUDT for the jdbc driver.

It requires the basetype of a type.

If I do create type testint8 as (i int8) and then select typbasetype
from pg_type where typname='testint8' the value is 0?

While I'm asking how can I find all of the user defined types, assuming
that the user is the owner of the cluster. I see that pg_dump can do
this ?
