v1.27.0Compare Source
Release date: Aug 12, 2025
Important changes:
livenessProbeTimeout(default: 30 seconds).Features:
Dynamic loading of PostgreSQL extensions: Introduced the
.spec.postgresql.extensionsstanza for mounting PostgreSQL extensions, packaged as OCI-compliant container images, as read-only and immutable volumes inside instance pods. This allows dynamic extension management without rebuilding base images. (#7991).Logical decoding slot synchronization in HA clusters: Added the
synchronizeLogicalDecodingfield underspec.replicationSlots.highAvailabilityto enable automatic synchronization of logical decoding slots across high-availability clusters, ensuring logical replication subscribers continue seamlessly after a publisher failover (#7931).Primary Isolation Check: Promoted to stable the liveness pinger experimental feature introduced in 1.26, adding the
.spec.probes.liveness.isolationChecksection to enable primary isolation checks in the liveness probe by default. This improves the detection and handling of primary connectivity issues in Kubernetes environments (#7845).Enhancements:
Introduced an opt-in experimental feature that enables quorum-based failover to improve safety and data durability during failover events. This feature, also called failover quorum, can be activated via the
alpha.cnpg.io/failoverQuorumannotation. (#7572).Added support for user maps for predefined users such as
streaming_replica, 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 thestreaming_replicarole (#7725).Added a new
PhaseFailurePluginphase in theClusterstatus to improve observability of plugin-related failures (#7988).Made the
Backup.specfield immutable after creation, ensuring consistency and predictability in backup operations (#7904).Added
fqdn-uriandfqdn-jdbc-urifields in the user secret to simplify the retrieval of fully qualified domain name-based connection strings (#7852).CNPG-I:
Added
Postgresinterface support to the CNPG-I operator, continuing the transition toward a plugin-based architecture (#7179).Added
metricscapabilities to the CNPG-I instance webserver, enabling metrics exposure directly from the instance for better observability (#8033).Fixes
barman-cloudplugin using theswitchoverstrategy. Former primary Pods now restart correctly after WAL archiving fails due to missing plugin support. (#8236)Supported versions
v1.26.1Compare Source
Release date: Jul 25, 2025
In memory of DJ Walker-Morgan.
Important Changes
CloudNativePG is moving toward a plugin-based, backup and recovery agnostic architecture (initiated in 1.26.0 with Barman Cloud). As part of this transition, the following fields in the
.statussection of theClusterresource are now deprecated:firstRecoverabilityPointfirstRecoverabilityPointByMethodlastSuccessfulBackuplastSuccessfulBackupByMethodlastFailedBackupAdditionally, the following Prometheus metrics are deprecated:
cnpg_collector_first_recoverability_pointcnpg_collector_last_available_backup_timestampcnpg_collector_last_failed_backup_timestampThese fields and metrics will no longer update when using plugin-based backups (e.g., Barman Cloud via CNPG-I). They remain functional for users still using in-core Barman Cloud and volume snapshot backups.
Changes
386and ARM (v5/v6/v7) architectures from thecnpgplugin build matrix, reducing the number of published binaries (#7648).Enhancements
Improved validation of
shared_buffersby correctly consideringHugePagessettings, ensuring accurate memory configuration checks (#7864).Set
oom_score_adjfor PostgreSQL worker processes to improve prioritization during out-of-memory situations (#7891).Added
fqdn-uriandfqdn-jdbc-urifields in user secrets to simplify application connection string management and align with DNS-based connection best practices (#7852).Added the
systemIDfield and related condition in theClusterstatus to track the PostgreSQL system identifier. (#7717).Fixes
Added a mutex in the connection pooler to protect concurrent access to the connections map, improving stability in high-concurrency environments (#7804).
Fixed replica cluster instance ordering by correctly detecting the designated primary, improving replica cluster stability and switchover operations (#8108).
Added support for reconciling
VolumeAttributesClassfor PVCs, enhancing storage compatibility and lifecycle management (#7885).Made the internal webserver routines non-blocking to improve responsiveness under load (#8071).
Fixed an issue where the
ensureReplicationClientLeafCertificateerror did not display the correctsecretNamein the not found message (#8086).Prevented invalid
ALTER SUBSCRIPTIONstatements by updating only PostgreSQL‑supported parameters; unsupported options likecopy_dataare ignored to avoid reconciliation failures (7844).Fixed an issue where the
bootstrap-controllerin the connection pooler did not applyresourcessettings correctly (#7922).Ensured online backups fail cleanly if the
targetPodbecomes unhealthy during backup, preventing partial or misleading backups (#7944).Ensured the Backup resource status is set properly after a failure, improving observability and scripting reliability (#7898).
Improved liveness probe handling to avoid unnecessary timeouts when they are not required (#7902).
v1.26.0Compare Source
Release date: May 23, 2025
Important Changes
CloudNativePG is now officially a CNCF project: CloudNativePG has been accepted into the Cloud Native Computing Foundation (CNCF), marking a significant milestone in its evolution. As part of this transition, the project is now governed under CloudNativePG, a Series of LF Projects, LLC, ensuring long-term sustainability and community-driven innovation. (#7203)
Deprecation of Native Barman Cloud Support: Native support for Barman Cloud backups and recovery is now deprecated and will be fully removed in CloudNativePG version 1.28.0. Although still available in the current release, users are strongly encouraged to begin migrating their existing clusters to the new Barman Cloud Plugin to ensure a smooth and seamless transition. The plugin should also be used for all new deployments. This change marks the first step toward making CloudNativePG a backup-agnostic solution, a goal that will be fully realized when volume snapshot support is also moved to a plugin-based architecture. (#6876)
End of Support for Barman 3.4 and Earlier: CloudNativePG no longer supports Barman versions 3.4 and earlier, including the capability detection framework. Users running older operand versions (from before April 2023) must update their operand before upgrading the operator to avoid compatibility issues. (#7220)
Hibernation Command Changes: The
hibernate onandhibernate offcommands in thecnpgplugin forkubectlnow serve as shortcuts for declarative hibernation. The previous imperative approach has been removed in favor of this method. Additionally, thehibernate statuscommand has been removed, as its functionality is now covered by the standardstatuscommand. Warning: Do not upgrade to version 1.26 of both the plugin and the operator unless you are prepared to migrate to the declarative hibernation method. (#7155)Features
Declarative Offline In-Place Major Upgrades of PostgreSQL: Introduced support for offline in-place major upgrades when a new operand container image with a higher PostgreSQL major version is applied to a cluster. During the upgrade, all cluster pods are shut down to ensure data consistency. A new job is created to validate upgrade conditions, run
pg_upgrade, and set up new directories forPGDATA, WAL files, and tablespaces as needed. Once the upgrade is complete, replicas are re-created. Failed upgrades can be rolled back declaratively. (#6664)Improved Startup and Readiness Probes for Replicas: Enhanced support for Kubernetes startup and readiness probes in PostgreSQL instances, providing greater control over replicas based on the streaming lag. (#6623)
Declarative management of extensions and schemas: Introduced the
extensionsandschemasstanzas in the Database resource to declaratively create, modify, and drop PostgreSQL extensions and schemas within a database. (#7062)Enhancements
Introduced an opt-in experimental feature to enhance the liveness probe with network isolation detection for primary instances. This feature can be activated via the
alpha.cnpg.io/livenessPingerannotation (#7466).Introduced the
STANDBY_TCP_USER_TIMEOUToperator configuration setting, allowing users to specify thetcp_user_timeoutparameter on all standby instances managed by the operator. (#7036)Introduced the
DRAIN_TAINTSoperator configuration option, enabling users to customize which node taints indicate a node is being drained. This replaces the previous fixed behavior of only recognizingnode.kubernetes.io/unschedulableas a drain signal. (#6928)Added a new field in the
statusof theClusterresource to track the latest known Pod IP (#7546).Added the
pg_extensionsmetric, providing information about installed PostgreSQL extensions and their latest available versions. (#7195)Added the
KUBERNETES_CLUSTER_DOMAINconfiguration option to the operator, allowing users to specify the domain suffix for fully qualified domain names (FQDNs) generated within the Kubernetes cluster. If not set, it defaults tocluster.local. (#6989)Implemented the
cnpg.io/validationannotation, enabling users to disable the validation webhook on CloudNativePG-managed resources. Use with caution, as this allows unrestricted changes. (#7196)Added support for patching PostgreSQL instance pods using the
cnpg.io/podPatchannotation with a JSON Patch. This may introduce discrepancies between the operator’s expectations and Kubernetes behavior, so it should be used with caution. (#6323)Added support for collecting
pg_stat_walmetrics in PostgreSQL 18. (#7005)Removed the
ENABLE_AZURE_PVC_UPDATESconfiguration, as it is no longer required to resize Azure volumes correctly. The Azure CSI driver includes the necessary fix as of version 1.11.0. (#7297)The
.spec.backup.barmanObjectStoreand.spec.backup.retentionPolicyfields are now deprecated in favor of the external Barman Cloud Plugin, and a warning is now emitted by the admission webhook when these fields are used in theClusterspecification (#7500).Added support for LZ4, XZ, and Zstandard compression methods when archiving WAL files via Barman Cloud (deprecated). (#7151)
CloudNativePG Interface (CNPG-I):
A plugin can now trigger instance rollouts by implementing the
EVALUATEverb, ensuring that plugin-induced changes are properly reconciled. (#7126)Introduced support for WAL recovery via CNPG-I plugins during snapshot restore. (#7284)
Security
imagePullPolicytoAlwaysfor the operator deployment to ensure that images are always pulled from the registry, reducing the risk of using outdated or potentially unsafe local images. (#7250)Fixes
Fixed native replication slot synchronization and logical replication failover for PostgreSQL 17 by appending the
dbnameparameter toprimary_conninfoin replica configurations (#7298).Fixed a regression in WAL restore operations that prevented fallback to the in-tree
barmanObjectStoreconfiguration defined in theexternalClustersource when a plugin failed to locate a WAL file (#7507).Improved backup efficiency by introducing a fail-fast mechanism in WAL archiving, allowing quicker detection of unexpected primary demotion and avoiding unnecessary retries (#7483).
Fixed an off-by-one error in parallel WAL archiving that could cause one extra worker process to be spawned beyond the requested number (#7389).
Resolved a race condition that caused the operator to perform two switchovers when updating the PostgreSQL configuration. (#6991)
Corrected the
PodMonitorconfiguration by adjusting thematchLabelsscope for the targeted pooler and cluster pods. Previously, thematchLabelswere too broad, inadvertently inheriting labels from the cluster and leading to data collection from unintended targets. (#7063)Added a webhook warning for clusters with a missing unit (e.g., MB, GB) in the
shared_buffersconfiguration. This will become an error in future releases. Users should update their configurations to include explicit units (e.g.,512MBinstead of512). (#7160)Treated timeout errors during volume snapshot creation as retryable to prevent unnecessary backup failures. (#7010)
Moved the defaulting logic for
.spec.postgresql.synchronous.dataDurabilityfrom the CRD to the webhook to avoid UI issues with OLM. (#7600)CloudNativePG Interface (CNPG-I):
Implemented automatic reloading of TLS certificates for plugins when they change. (#7029)
Ensured the operator properly closes the plugin connection when performing a backup using the plugin. (#7095, #7096)
Fixed an issue that prevented WALs from being archived on a former primary node when using a plugin. (#6964)
Improved performance and resilience of CNPG-I by removing timeouts for local plugin operations, avoiding failures during longer backup or WAL archiving executions (#7496).
cnpgplugin:Increased the buffer size in the
logs prettycommand to better handle larger log output (#7281).Ensured the
plugin-nameparameter is required for plugin-based backups and disallowed for non-plugin backup methods (#7506).Ensured that the primary Pod is recreated during an imperative restart when
primaryUpdateMethodis set torestart, aligning its definition with the replicas. (#7122)Changes
Updated the default PostgreSQL version to 17.5 for new cluster definitions. (#7556)
Updated the default PgBouncer version to 1.24.1 for new
Poolerdeployments (#7399).Supported versions
