The `extra` kwarg is used in a few places in the `PostgresHook`. For example line 91 [here](https://github.com/apache/airflow/blob/main/airflow/providers/postgres/hooks/postgres.py#L91). The usage of extras is documented [here](https://airflow.apache.org/docs/apache-airflow-providers-postgres/stable/_api/airflow/providers/postgres/hooks/postgres/index.html). I believe it is inherited from the [connection class](https://github.com/apache/airflow/blob/main/airflow/models/connection.py). -- This is an automated message from the Apache Git Service.
