**Apache Airflow version**: 2.1.0
**Kubernetes version (if you are using kubernetes)** (use `kubectl version`):1.21
**Environment**:
- **Cloud provider or hardware configuration**:
- **OS** (e.g. from /etc/os-release):
- **Kernel** (e.g. `uname -a`):Linux workspace
- **Install tools**:
- **Others**:
**What happened**:
Running PostgresOperator errors out with 'PostgresHook' object has no attribute 'schema'.
I tested it as well with the code from PostgresOperator tutorial in https://airflow.apache.org/docs/apache-airflow-providers-postgres/stable/operators/postgres_operator_howto_guide.html
This is happening since upgrade of apache-airflow-providers-postgres to version 2.1.0

Can you provide output of airflow providers list command? I have the impression that the latest package requires Airflow 2.2.

For now downgrading Postgres operator to 2.0.0 should fix the problem.
