fixes (8)

  • - Improved resilience of all probe types (liveness, readiness, and startup) to transient Kubernetes API server connectivity issues. Probes now use a caching mechanism that falls back to cached cluster definitions during brief network interruptions, preventing unnecessary pod restarts and probe failures. ([\#9148](https://github.com/cloudnative-pg/cloudnative-pg/pull/9148)) <!-- 1.27 -->
  • - Fixed the CheckEmptyWalArchive safeguard to run correctly when restoring from a volume snapshot using CNPG-I backup/WAL plugins (e.g., plugin-barman-cloud). Previously, this check was skipped for plugin-based implementations. ([\#9306](https://github.com/cloudnative-pg/cloudnative-pg/pull/9306)) <!-- 1.27 1.26 1.25 -->
  • - Improved error reporting when ImageCatalog retrieval fails. The operator now emits a Warning event and logs errors for all failure types, not just NotFound errors, improving visibility into configuration issues. ([\#9266](https://github.com/cloudnative-pg/cloudnative-pg/pull/9266)) <!-- 1.27 -->
  • - Fixed TLS certificate verification issues when connecting to CNPG-I plugins by adding the cnpg.io/pluginServerName annotation. This allows customizing the DNS name used for certificate verification in environments where the plugin's certificate uses a different DNS name than the Service name. ([\#9222](https://github.com/cloudnative-pg/cloudnative-pg/pull/9222)) <!-- 1.27 1.26 1.25 -->
  • - Fixed an issue where the instance manager controller could fail to restart after an error, reporting a "controller already exists" message. The controller now uses SkipNameValidation for subsequent initialization attempts. Contributed by @mateusoliveira43. ([\#9123](https://github.com/cloudnative-pg/cloudnative-pg/pull/9123)) <!-- 1.27 1.26 1.25 -->
  • - Fixed incorrect WAL restore path handling in plugins when the destination path is absolute, preventing path duplication issues. Contributed by @Endevir. ([\#9093](https://github.com/cloudnative-pg/cloudnative-pg/pull/9093)) <!-- 1.27 1.26 1.25 -->
  • - Fixed backup failures in complex pod definitions by reliably selecting the postgres container by name instead of by index. Contributed by @Joda89. ([\#8964](https://github.com/cloudnative-pg/cloudnative-pg/pull/8964)) <!-- 1.27 1.26 1.25 -->
  • - Fixed bugs in cnpg report log collection, especially when fetching previous logs. The collector now correctly fetches previous and current logs in separate requests and gracefully handles missing previous logs (e.g., on containers with no restart history), ensuring current logs are always collected. ([\#8992](https://github.com/cloudnative-pg/cloudnative-pg/pull/8992)) <!-- 1.27 1.26 1.25 -->

value changes (3)

  • - Updated the default PostgreSQL version to 18.1-system-trixie. ([\#9178](https://github.com/cloudnative-pg/cloudnative-pg/pull/9178)) <!-- 1.27 1.26 1.25 -->
  • - Updated the default PgBouncer version to **1.25.1** for new Pooler deployments. ([\#9367](https://github.com/cloudnative-pg/cloudnative-pg/pull/9367)) <!-- 1.27 1.26 1.25 -->
  • - Added the PostgreSQL majorVersion to the Backup object's status for easier identification and management. ([\#8464](https://github.com/cloudnative-pg/cloudnative-pg/pull/8464)) <!-- 1.27 1.26 -->

additions (2)

  • - Added the PGBOUNCER_IMAGE_NAME operator configuration parameter to allow overriding the default PgBouncer image. This is useful for air-gapped environments or when using internal registries. ([\#9232](https://github.com/cloudnative-pg/cloudnative-pg/pull/9232)) <!-- 1.27 1.26 1.25 -->
  • - Added a --timeout flag to the kubectl cnpg status command for configuring the timeout for filesystem operations such as calculating cluster size. The default remains 10 seconds but can be adjusted for large clusters where operations may take longer. ([\#9201](https://github.com/cloudnative-pg/cloudnative-pg/pull/9201)) <!-- 1.27 -->

constraints (1)

  • - Fixed the CREATE PUBLICATION SQL generation for multi-table publications to be backward-compatible with PostgreSQL 13+. The previously generated syntax was only valid for PostgreSQL 15+ and caused syntax errors on older versions. ([\#8888](https://github.com/cloudnative-pg/cloudnative-pg/pull/8888)) <!-- 1.27 1.26 1.25 -->
