I still think we should get rid of these helper methods if possible. See https://github.com/rails/rails/pull/10939#issuecomment-23920944 for context.

This could look like:

```ruby
module ReferentialIntegrity
  SAVEPOINT_NAME = "disable_referential_integrity"

  def ....
    # ...
    create_savepoint(SAVEPOINT_NAME)
    # ...
  end
end
```

However before we can replace this I need to go over it with Rafael to see if we can change the interface of `create_savepoint`. I'll keep you posted on the progress.
