What's the correct syntax for remove_index in a Rails 3.1.0 migration?

Question

I\'m in the process of adding Devise to an existing Rails app, with a Users table already defined. The devise generator pushed out the following migration:

You can also remove the index specifying the columns, which from my point of view is less error prone than writing the name

remove_index :actions, :column => [:user_id, :action_name]
