I just need to know what to add to the TODO list, and so we can answer
people who are going to ask for this functionality.  Added to TODO:

    * Allow reporting of which objects are in which tablespaces
    * Allow database recovery where tablespaces can't be created
        o Add ALTER TABLESPACE to change location, name, owner
        o Allow objects to be moved between tablespaces

I think this all the items still needed.
