EDB CloudNativePG Cluster 1.27.0 release notes v1.27.0

The .spec.postgresql.extensions stanza allows you to mount PostgreSQL extensions as read-only and immutable volumes inside instance pods. This enables dynamic extension management without rebuilding base images.

Added the synchronizeLogicalDecoding field under spec.replicationSlots.highAvailability to enable automatic synchronization of logical decoding slots across high-availability clusters. This ensures that logical replication subscribers continue seamlessly after a publisher failover.

Promoted to stable the liveness pinger experimental feature introduced in 1.26, adding the .spec.probes.liveness.isolationCheck section to enable primary isolation checks in the liveness probe by default. This improves the detection and handling of primary connectivity issues in Kubernetes environments.

...to improve safety and data durability during failover events. This feature, also called failover quorum, can be activated via the alpha.k8s.enterprisedb.io/failoverQuorum annotation.

...allowing the use of self-managed client certificates with different Common Names in environments with strict policies or shared CAs, while still enabling replicas to join clusters using the streaming_replica role.

...to improve observability of plugin-related failures.

...ensuring consistency and predictability in backup operations.

...to simplify the retrieval of fully qualified domain name-based connection strings.

...continuing the transition toward a plugin-based architecture.

...enabling metrics exposure directly from the instance for better observability.

Former primary Pods now restart correctly after WAL archiving fails due to missing plugin support.
