This page is only applicable to accounts created before May 15, 2023 or if you asked Heroku Support to enable auto-provisioning for your account.
Database Auto-Provisioning
The Python buildpack automatically provisions a Heroku Postgres database on the first deploy of your app if:
- You created your account before May 15, 2023 or if you asked Heroku Support to enable auto-provisioning for your account
- A
manage.pyfile exists in the root of the app source - Both the
Djangoandpsycopg2packages are installed
Automatic provisioning of a database also populates your app’s DATABASE_URL config var.
A Heroku Postgres database is not automatically provisioned for other Python apps, but you can provision one manually.
