Upgrade Notices

PostgreSQL has been updated from 18.3 to 18.4.

Platform One does not support the bundled in-cluster PostgreSQL database for production deployments. The bundled database should only be used for development, testing, or CI environments.

Although this is a minor PostgreSQL version update, users should follow standard database maintenance practices and ensure appropriate backups are taken before upgrading. Users relying on the bundled in-cluster database are responsible for backing up and validating their data prior to performing the upgrade.
