Version 1.23.1

Release date: Apr 29, 2024

Fixes:

  • Corrects the reconciliation of PodMonitor resources, which was failing due to a regression (#4286)

Version 1.23.0

Release date: Apr 24, 2024

Features:

  • PostgreSQL Image Catalogs: Introduced ClusterImageCatalog and ImageCatalog CRDs to manage operand container images based on PostgreSQL major version. This is facilitated through the Cluster ’s .spec.imageCatalogRef stanza . This feature provides an alternative to the imageName option and will eventually replace it as the default method to define operand container images.

  • User-Defined Replication Slots: Enhanced the synchronization of physical replication slots to cover user-defined replication slots on the primary, via the newly introduced stanza replicationSlots.synchronizeReplicas .

  • Configuration of Pod Disruption Budgets (PDB): Introduced the .spec.enablePDB field to disable PDBs on the primary instance, allowing proper eviction of the pod during maintenance operations. This is particularly useful for single-instance deployments. This feature is intended to replace the node maintenance window feature.

Enhancements:

  • Users now have the capability to transition an existing cluster into replica mode, simplifying cross-datacenter switchover operations (#4261)

  • Users can now customize the connection pooler service, including its type, labels, and annotations (#3384)

  • Users can now configure the wal_log_hints PostgreSQL parameter (#4218) (#4218)

  • Fully Qualified Domain Names (FQDN) in URIs for automatically generated secrets (#4095)

  • Cleanup of instance Pods not owned by the Cluster during Cluster restore (#4141)

  • Command output of the plugin’s status command to show the status of PDBs (#4319)

  • Error detection when invoking barman-cloud-wal-restore in recovery bootstrap (#4101)

Fixes:

  • Ensured that before a switchover, the elected replica is in streaming replication (#4288)

  • Correctly handle parsing errors of instances’ LSN when sorting them (#4283)

  • Recreate the primary Pod if there are no healthy standbys available to promote (#4132)

  • Cleanup PGDATA in case of failure of the restore job (#4151)

  • Reload certificates on configuration update (#3705)

  • cnpg plugin for kubectl :

    • Improve the arguments handling of destroy , fencing , and promote plugin commands (#4280)

    • Correctly handle the percentage of the backup progress in cnpg status (#4131)

    • Gracefully handle databases with no sequences in sync-sequences command (#4346)
