Question 1

What happens when Heroku Postgres reaches end of life?

Accepted Answer

When Heroku Postgres reaches end of life, it stops receiving security patches, bug fixes, and new features. Currently, 4 Heroku Postgres versions are already EOL. The latest supported version is Heroku Postgres 18. Running an EOL version exposes your systems to unpatched security vulnerabilities with no official fix available.

Question 2

Is Heroku Postgres 18 still supported?

Accepted Answer

Yes. Heroku Postgres 18 is actively supported. It receives security patches and bug fixes. Check the version table above for the full list of supported Heroku Postgres releases and their exact end-of-life dates.

Question 3

Is it safe to use Heroku Postgres after end of life?

Accepted Answer

No. Running Heroku Postgres after EOL is not safe for production systems. Once a version reaches end of life, newly discovered CVEs are published publicly but never patched — leaving your systems permanently exposed. The only safe path is upgrading to an actively supported Heroku Postgres release.

Question 4

How to upgrade from Heroku Postgres 14 to Heroku Postgres 18.x?

Accepted Answer

To upgrade Heroku Postgres from 14 to 18, start by reviewing the official migration guide for breaking changes and deprecated APIs. Update any dependencies that pin to a specific major version, then test your application against the new release in a staging environment. Run your full test suite before deploying, and always prepare a rollback plan. The earlier you start, the more time you have to resolve compatibility issues before your current version reaches end of life.

Question 5

When is the next Heroku Postgres LTS version?

Accepted Answer

Not all Heroku Postgres releases have a designated LTS status. Check the version table above — LTS releases are marked with an "LTS" badge. Refer to the official Heroku Postgres release policy for information on upcoming long-term support versions.

Question 6

How long does Heroku Postgres support each version?

Accepted Answer

On average, Heroku Postgres supports each release for approximately 50 months (~4.2 years).  The exact EOL date for each version is listed in the table above.
