15  # When using the methods "add_concurrent_index" or "add_column_with_default"

17  # existing transaction. When using "add_concurrent_index" make sure that this
18  # method is the _only_ method called in the migration, any other changes
19  # should go in a separate migration. This ensures that upon failure _only_ the
20  # index creation fails and can be retried or reverted easily.

23  # comments:
