  # constant and define a short and easy to understand explanation as to why the
  # migration requires downtime.

  # When using the methods "add_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" make sure that this
  # method 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 fails and can be retried or reverted easily.
  #
  # To disable transactions uncomment the following line and remove these
  # comments:
  # disable_ddl_transaction!
