  # When using the methods "add_concurrent_index", "remove_concurrent_index" or
  # "add_column_with_default" you must disable the use of transactions
  # as these methods can not run in an existing transaction.
  # When using "add_concurrent_index" or "remove_concurrent_index" methods make sure
  # that either of them is the _only_ method called in the migration,
  # any other changes should go in a separate migration.
  # This ensures that upon failure _only_ the index creation or removing fails
  # and can be retried or reverted easily.
  #
  # To disable transactions uncomment the following line and remove these
  # comments:
  # disable_ddl_transaction!
