I think that, if you want to push a refactored UUID type for PostgreSQL 
8.2, that you'd better separate your database design arguments from your 
inclusion arguments.   

For example, you might get my agreement that it would be useful to have a 
UUID as a core type; you would *never* get my agreement to recommend using 
UUID to newbies.   I have seen *far* too many abuses of UUIDs in really 
bad database design.   People who use them should be experienced enough to 
know what they're doing.
