Rals + PostrgreSQL cascading delete?

Hello. My deletion is done directly in the database through ActiveRecord::Base.connection.execute.
Therefore it is necessary to make values ​​of foreign keys (foreing_key) ON DELETE CASCADE ?
How to implement this correctly and how to specify this value when creating new tables in migration? Thank you.
