Changes to Heroku Postgres auto-provisioning behavior

Change effective on 25 May 2023

We made changes to how the automatic provisioning of Heroku Postgres works.

Accounts created after May 15, 2023, don’t automatically provision a Postgres database on an app’s first deployment.

Accounts created before this date continue to automatically provision a database for Ruby, Python Django, Java and Scala apps if the apps contain a Postgres database adapter dependency.

You can always manually provision a Postgres database at any time.
