      # Add enumeration support for schema statement creation. This
      # will have to be adapted for every adapter if the type requires
      # anything by a list of allowed values. The overrides the standard
      # type_to_sql method and chains back to the default. This could 
      # be done on a per adapter basis, but is generalized here.
      #
      # will generate enum('a', 'b', 'c') for :limit => [:a, :b, :c]
