Update to Heroku Postgres Mini and Basic end-of-life

Change effective on 21 May 2024

As previously announced, we’re deprecating mini and basic Heroku Postgres plans on the Essential tier. We’re changing the end-of-life (EOL) date from May 22, 2024 to May 29, 2024.

If your review apps and CI apps use mini or basic databases in the app.json, you must update them to the new Essential-tier plans before the EOL date. If not, no action is required as we’ll migrate these add-ons to the new Essential-tier plans.

See our schedule for deprecating all mini and basic databases in Mini and Basic Deprecation Details for more information.
