  # Limit shouldn't affect "#{col}_type" column in polymorphic reference.
  # But don't change value if it isn't simple 'true'.
  # Examples:
  #   t.references :subject, null: false, polymorphic: true ==> t.integer :subject_id, limit: 8, null: false
  #                                                             t.string  :subject_type, null: false
  #   t.references :subject, polymorphic: { limit: 120 }    ==> t.integer :subject_id, limit: 8
  #                                                             t.string  :subject_type, limit: 120
