Update: If I manually add the column in using pgAdmin (as a uuid type
of course), the program actually runs (I can create new rows and
display data).. So RoR does support this type (probably gets
marshalled as a string??) but I guess the ActiveRecord schema
generation stuff just doesn't support uuid. Hmmm.
