ISTM that the ultimate would be a 'create table (...._) without storage' 
(or some'm) and make 'create type' an alternate syntax for SQL 
conformance.  For various reasons, we've internally adopted using create 
table for all composites and use a c-like naming convenstion of 
appending _t to such beasts.

I'll just throw a little meat into the pack wolves....constraints....?
