Rails 3.1 reversible migrations and change_table

[Szymon Nowak]

Hi,

is the following migration really supposed to be irreversible?

class AddColumnsToUsers < ActiveRecord::Migration

  def change

    change_table :users do |t|

      t.integer :foo

      t.integer :bar

    end

  end

end

I'm using Rails 3.1 RC6 and when trying to redo this migration I'm getting ActiveRecord::IrreversibleMigration error.

Cheers,

Szymon
