What are the best practices for database connection pooling on Heroku?

To optimize database connection pooling on Heroku, consider using a connection pooler like PgBouncer, set appropriate pool sizes, and monitor your database performance.

How do I configure PgBouncer for my Heroku app?

You can configure PgBouncer by adding it to your Heroku app as an add-on, then setting environment variables for connection settings.

What should I set the pool size to?

The pool size should typically be set to a value that is a fraction of your database's max connections, often around 20-25%.

Are there any common pitfalls to avoid?

Yes, avoid setting the pool size too high, which can lead to connection saturation, and ensure your app handles connection timeouts gracefully.
