Heroku Postgres now supports heroku addons:upgrade

Change effective on 21 July 2020

Heroku Postgres database plans (for non-hobby databases) now support the heroku addons:upgrade mechanism for changing a database’s plan in place without requiring a follower changeover or heroku pg:copy command. Read more here.

Using heroku addons:upgrade offers several advantages:

  • Any followers of your database get pointed at the new primary without having to manually build replacements
  • It uses the mechanisms described in our Faster Maintenances article to achieve less downtime and customer impact
  • Less toil: heroku addons:upgrade is a smaller number of commands or API calls to perform
