added additional documentation on accessing postgres service

---

This architecture provides a solid foundation for building a more complex web application. Future enhancements might include additional user roles, improved UI, or REST API support.

## Additional Notes

Enter the postgres database container using,

```bash

docker exec -it tornado-backend_postgres_1 psql -U blog -d blog

```

1) Check the entries of the authors table,

```bash

SELECT * from authors;

```

Which results in, e.g., 

```psql

blog=# SELECT * from authors;

 id |         email         |     name      |                       hashed_password

                     |         published          |          updated
