Looking at the tables in psql, it looks like dag_run.id is just a sequential integer. My thought was to add a parse_deadline method to the dagrun constructor [here](https://github.com/apache/airflow/blob/main/airflow/models/dagrun.py#L263). At that point we know the dag_id and the run_id but won't know the sequential id that will be assigned to it yet, right? -- This is an automated message from the Apache Git Service.
