How can I set up automatic backups for the data stored in a PostgreSQL database used by my Django web application?

To set up automatic backups for PostgreSQL in a Django application, you can use the `pg_dump` tool for database backup and automate the process using cron jobs. Schedule the cron jobs to run at regular intervals, ensuring consistent backups. Remember to store these backups in a safe, preferably offsite location to ensure maximum security. Additionally, consider using PostgreSQL's built-in replication features for real-time backups. Last but not least, regularly test your backup and restore process to ensure data integrity and the effectiveness of your backup strategy.
