heroku で rake db:migrate を実行したところ、次のエラーが発生しました

==  AlterBodyForDocuments: migrating ==========================================
-- change_column(:documents, :body, :mediumtext)
rake aborted!
An error has occurred, this and all later migrations canceled:

PGError: ERROR:  type "mediumtext" does not exist
: ALTER TABLE "documents" ALTER COLUMN "body" TYPE mediumtext

Tasks: TOP => db:migrate
(See full trace by running task with --trace)

これは私の AlterBodyForDocuments 移行です:

class AlterBodyForDocuments < ActiveRecord::Migration
  def change
    change_column :documents, :body, :mediumtext
  end
end

mediumtext は mysql のものだと思います

heroku は postgresql を使用します

:text代わりに使用
