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.
