Heroku PostgreSQL 10 deprecation - Update

Change effective on 16 December 2022

As previously announced, Heroku PostgreSQL 10 is deprecated, but we are adjusting the date when we will begin forced upgrades to March 10th, 2023. We urge customers to upgrade their database themselves prior to the new date so that they can test application compatibility and perform the migration on their own schedule. Any forced upgrades are potentially subject to hours of downtime.

Deprecated Postgres databases will be automatically upgraded to the next available version of Postgres after the new date. This deprecation is part of our documented version support policy.
