A new PostgreSQL blog post/announcement has been posted!

The CloudNativePG Community is excited to announce the release of CloudNativePG 1.27.0, bringing powerful new features, stability improvements, and extended capabilities for running PostgreSQL in Kubernetes.

Highlights in 1.27.0

Dynamic Loading of PostgreSQL Extensions

You can now use the new .spec.postgresql.extensions field to mount PostgreSQL extensions—packaged as OCI-compliant container images—as read-only, immutable volumes in instance pods. This enables dynamic extension management without rebuilding base images, offering faster, more flexible extension deployments.

Logical Decoding Slot Synchronization

A new synchronizeLogicalDecoding option under spec.replicationSlots.highAvailability introduces automatic synchronization of logical decoding slots across high-availability clusters. This ensures that logical replication subscribers can continue seamlessly after a publisher failover, improving reliability and integration with Change Data Capture (CDC) tools.

Primary Isolation Check — Now Stable

The liveness pinger, introduced experimentally in 1.26, is now a stable feature. With .spec.probes.liveness.isolationCheck enabled by default, the liveness probe now performs primary isolation checks to improve detection and handling of primary connectivity issues in Kubernetes environments.

Other Enhancements

This release also includes:

• Quorum-based failover (experimental) — an opt-in feature that improves safety and data durability during failover events through synchronous replication. Learn more.
• User maps for predefined users — including streaming_replica, enabling the use of self-managed client certificates with different Common Names in ...
