Well, I continue to ask for pointers to pgsql documentation on how one is expected to work with these udt types in JDBC. Still waiting on an answer.

Christopher Smith To be honest I have forgotten the details because its been so long since I worked on fixing the code in EnumType. But the code was a mess. I understand that it may have worked for you on pgsql, but it caused problems everywhere else. So I fixed it. If you can give me specifics as to what does not work on pgsql and why I can try to resolve this for pgsql. But I am not a pgsql user/expert/guru/etc. Pgsql has its own ideas how things should be done.
