Well, if you have debugged this, it'd be nice if you could share more information (e.g. backtraces, etc.) otherwise others can just guess what you saw. And that makes it much harder to help you.
I see you defined the data type as PASSEDBYVALUE, but you haven't specified INTERNALLENGTH, so it's -1 (i.e. variable length). Obviously, that can't be passed by value - not sure if this is intentional or just a case of CREATE TYPE not checking it.
BTW it's customary not to top post - inline replies are much easier to follow, as it makes clearer which parts you respond to. And please make sure that you're responding to the mailing list, not just directly to the other person.
