Great questions. I wish I could answer them... Take a look in
the contrib/ directory for examples of various user defined types.
contrib/cube and contrib/lo in particular deal (in different ways)
with user types of varying size.

Hopefully others more knowledgeable will address your questions
directly. I'm certainly interested in the answers to many of them ;-)
