Overview

ActiveRecord migration methods (e.g., #create_table, #remove_column, etc.) are actually defined on the connection classes used by ActiveRecord. Here, we make sure that we get a chance to patch any connection used in any migration properly, so that we can add our migration support to it. See LowCardTables::ActiveRecord::Migrations for more information.
