Heroku has ended LTS support for PostgreSQL 14. Supported versions are now 15, 16, and 17.
This update upgrades the n8n-heroku database to PostgreSQL 16 to maintain compatibility and support.

Notes:

  • Updated Heroku Postgres add-on to v16.
  • Verified schema and data compatibility.
  • Tested app connectivity post-upgrade.

Note

Upgrades Heroku Postgres to v16, pins Docker base image to n8nio/n8n:stable, and updates the README deploy button link.

  • Infrastructure:
    • Upgrade Heroku Postgres add-on in app.json from version 14 to 16.
    • Pin Docker base image in Dockerfile from n8nio/n8n:latest to n8nio/n8n:stable.
  • Docs:
    • Update README.md deploy button URL to point to yunus25jmi1/n8n-heroku.

Bug: Heroku Button Links to Incorrect Fork

The "Deploy to Heroku" button in README.md now links to a personal fork (yunus25jmi1/n8n-heroku) instead of the official repository. This is inconsistent with app.json and could cause users to deploy from an unintended source, appearing unrelated to the PR's PostgreSQL upgrade.
