Ok the idea here though is that if you have the same table multiple times, and you *aren't* displaying the column, just the table, the table should be de-duped on name.   if i had `with_lockmode(of=[User.id, User.name])`, id want Oracle to say `FOR UPDATE OF users.id, users.name` but PG should say `FOR UPDATE OF users`. 

in the most recent changesets you'll also see support for table aliases and select "adaptation" which is pretty important with the ORM.
