This plugin maintains unique primary key ID through ALL of your models

1. ./script/plugin install git://github.com/maxlapshin/single_primary_key.git
2. ./script/generate migration single_id
3. Replace contents of migration class with extend SinglePrimaryKey::Migration, i.e.:

class SingleId < ActiveRecord::Migration
  extend SinglePrimaryKey::Migration
end

4. rake db:migrate
5. voila! MySQL and Postgres now will have unique ID. Thus you can safely use LEFT JOIN with
polymorpic associations.
