The CloudNativePG Community is thrilled to announce the first release candidate of CloudNativePG 1.28! This preview release provides an opportunity to explore new features and enhancements before the final version is officially launched. While refinements may still occur, here’s a look at what’s new.

Key Features

Quorum-Based Failover Promoted to Stable

The quorum-based failover feature, introduced experimentally in 1.27, has been promoted to a stable API. This data-driven failover mechanism is now configured via the spec.postgresql.synchronous.failoverQuorum field, graduating from the previous alpha.cnpg.io/failoverQuorum annotation. This enhances failover safety and data durability for high-availability clusters.

Declarative Foreign Data Management

We introduced comprehensive declarative management for Foreign Data Wrappers (FDW) by extending the Database CRD. This feature adds the .spec.fdws and .spec.servers fields, allowing you to manage FDW extensions and foreign servers directly from the Database resource. This work was implemented by Ying Zhu (@EdwinaZhu) as part of the LFX Mentorship Program 2025 Term 2.

There’s More…

Explore other improvements in this release, including:

• Introduced granular control over fine-grained security contexts, allowing securityContext at the pod level and containerSecurityContext for individual containers.
• Allowed providing custom TLS for PgBouncer for both client-to-pooler and pooler-to-server connections, taking precedence over operator-generated certificates.
• Added optional TLS support for the operator’s metrics server, enabled via the METRICS_CERT_DIR environment variable.
• Enabled the cnpg report operator command to work with minimal, least-privileged access, gracefully handling permission errors.
• Introduced the alpha.cnpg.io/unrecoverable=true annotation to automatically delete and recreate a replica pod and its PVCs.
