2024-05-12: Upgrade Heroku Database by September

[ejaxon]

Email from Heroku:

PostgreSQL 13 reaches End of Life on 2024-Oct-29. Due to security and operational concerns, Heroku cannot run unsupported software as a service. Therefore, the following database will need to be updated before 2024-Oct-29:

 App: bc-court-reminders
 Database: postgresql-triangular-29832::HEROKU_POSTGRESQL_MAUVE_URL

You have two options:

• Before 2024-Sep-29, you can perform an upgrade to version 14 or more. Typically, you will have around 10 minutes downtime. You may want additional time to ensure that everything works properly after the upgrade. This dev-center article provides instructions on performing the upgrade: https://devcenter.heroku.com/articles/upgrading-heroku-postgres-databases
• After 2024-Sep-29, we will schedule an automatic upgrade to 16. This forced upgrade will incur significant downtime for the database and associated app(s), which can reach 12 hours in extreme cases.

All upgrades must be completed by 2024-Sep-29. We reserve the right to deprovision any database not upgraded at that time.
