v1.25.1

Compare Source

Release Date: February 28, 2025

Enhancements

• Introduced a startup probe for the operator to enhance reliability and prevent premature liveness probe failures during initialization. (#​7008)
• Added support for using the -r service with the Pooler. (#​6868)
• Introduced an optional --ttl flag for the pgbench plugin, enabling automatic deletion of completed jobs after a user-defined duration. (#​6701)
• Marked known error messages from the Azure CSI Driver for volume snapshots as retryable, improving resilience. (#​6906)
• Updated the default PostgreSQL version to 17.4 for new cluster definitions. (#​6960)

Security

• The operator image build process has been enhanced to strengthen security and transparency. Images are now signed with cosign, and OCI attestations are generated, incorporating the Software Bill of Materials (SBOM) and provenance data. Additionally, OCI annotations have been added to improve traceability and ensure the integrity of the images.

Bug Fixes

• Fixed inconsistent behavior in default probe knob values when .spec.probes is defined, ensuring users can override all settings, including failureThreshold. If unspecified in the startup probe, failureThreshold is now correctly derived from .spec.startupDelay / periodSeconds (default: 10, now overridable). The same logic applies to liveness probes via .spec.livenessProbeTimeout. (#​6656)
• Managed service ports now take precedence over default operator-defined ports. (#​6474)
• Fixed an issue where WAL metrics were unavailable after an instance restart until a configuration change was applied. (#​6816)
• Fixed an issue in monolithic database import where role import was skipped if no roles were specified. (#​6646)
• Added support for new metrics introduced in PgBouncer 1.24. (#​6630)
• Resolved an issue where Database, Publication, and Subscription CRDs became stuck in cluster resource has been deleted, skipping reconciliation after cluster rehydration. This patch forces status.observedGeneration to zero, ensuring proper reconciliation. (#​6607)
• Improved handling of replication-sensitive parameter reductions by ensuring timely reconciliation after primary server restarts. (#​6440)
• Introduced a new isWALArchiver flag in the CNPG-I plugin configuration, allowing users to designate a plugin as a WAL archiver. This enables seamless migration from in-tree Barman Cloud support to the plugin while maintaining WAL archive consistency. (#​6593)
• Ensured override.conf is consistently included in postgresql.conf during replica cluster bootstrapping, preventing replication failures due to missing configuration settings. (#​6808)
• Ensured override.conf is correctly initialized before invoking pg_rewind to prevent failures during primary role changes. (#​6670)
• Enhanced webhook responses to return both warnings and errors when applicable, improving diagnostic accuracy. (#​6579)
• Ensured the operator version is correctly reconciled. (#​6496)
• Improved PostgreSQL version detection by using a more precise check of the data directory. (#​6659)
• Volume Snapshot Backups:
  • Fixed an issue where unused backup connections were not properly cleaned up. (#​6882)
  • Ensured the instance manager closes stale PostgreSQL connections left by failed volume snapshot backups. (#​6879)
  • Prevented the operator from starting a new volume snapshot backup while another is already in progress. (#​6890)
• cnpg plugin:
  • Restored functionality of the promote plugin command. (#​6476)
  • Enhanced kubectl cnpg report --logs <cluster> to collect logs from all containers, including sidecars. (#​6636)
  • Ensured pgbench jobs can run when a Cluster uses an ImageCatalog. (#​6868)

Technical Enhancements

• Added support for Kubernetes client-gen, enabling automated generation of Go clients for all CloudNativePG CRDs. (#​6695)

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
