Trance, I had a similar problem and solve it. It is not related to your DB Engine. In the ruby migration add the :id => false to your table definition, because you don't need it at all. This is for tables that are a join table between two tables.

create_table "categories_posts", :id => false, :force => true do |t|
t.column ...
