Task

As an engineer working on RHDH, I want to update the RHDH Helm Chart configuration to deploy PostgreSQL 16 for the integrated database so that Helm-based deployments use the latest Red Hat supported PostgreSQL version.

Background

The integrated database (deployed by Helm Chart) needs to be upgraded from the current PostgreSQL version to PostgreSQL 16. This is because no Red Hat supported PostgreSQL 17 container image is available, but PostgreSQL 16 is the latest version with official Red Hat container images.

This task is part of the epic RHIDP-9570 (Upgrade integrated database to PostgreSQL 16).

Dependencies and Blockers

• Red Hat PostgreSQL 16 container image availability
• RHIDP-10941 - Operator update (coordinate changes)

QE impacted work
Documentation impacted work

Acceptance Criteria

• Helm Chart values updated to use PostgreSQL 16 container image
• New Helm deployments create PostgreSQL 16 database by default
• Existing deployments continue to work (backward compatibility)
• Configuration changes documented in PR
