Code Review
This pull request enhances the streaming executor's progress bar by displaying the names of the backpressure policies that are currently active. The changes are well-implemented across the physical operator interface and the streaming executor state management. The addition of new tests ensures the correctness of this new feature. I have one suggestion to improve the code by using dataclasses.field(default_factory=list) for initializing mutable default values, which is a more idiomatic approach.
