* feat(logical-backup): add configurable job history limits and TTL Adds three new configuration options for logical backup cronjobs: - logical_backup_successful_jobs_history_limit (default: 3) - logical_backup_failed_jobs_history_limit (default: 3) - logical_backup_ttl_seconds_after_finished (default: 86400) These options control how many completed/failed backup jobs are retained by Kubernetes and when finished jobs are automatically deleted. This prevents accumulation of old backup jobs and pods in namespaces with many PostgreSQL clusters. Also updates the CronJob comparison logic to detect changes in these new fields and trigger reconciliation when needed. Closes zalando/postgres-operator#1092 * add added the 3 new fieldson crd * updated gen api --------- Co-authored-by: Jairo Llopis <jairo@moduon.team> Co-authored-by: Felix Kunde <felix-kunde@gmx.de> |

Postgres Operator
The Postgres Operator delivers an easy to run highly-available PostgreSQL clusters on Kubernetes (K8s) powered by Patroni. It is configured only through Postgres manifests (CRDs) to ease integration into automated CI/CD pipelines with no access to Kubernetes API directly, promoting infrastructure as code vs manual operations.
Operator features
- Rolling updates on Postgres cluster changes, incl. quick minor version updates
- Live volume resize without pod restarts (AWS EBS, PVC)
- Database connection pooling with PGBouncer
- Support fast in place major version upgrade. Supports global upgrade of all clusters.
- Pod protection during bootstrap phase and configurable maintenance windows
- Restore and cloning Postgres clusters on AWS, GCS and Azure
- Additionally logical backups to S3 or GCS bucket can be configured
- Standby cluster from S3 or GCS WAL archive
- Configurable for non-cloud environments
- Basic credential and user management on K8s, eases application deployments
- Support for custom TLS certificates
- UI to create and edit Postgres cluster manifests
- Compatible with OpenShift
PostgreSQL features
- Supports PostgreSQL 18, starting from 14+
- Streaming replication cluster via Patroni
- Point-In-Time-Recovery with pg_basebackup / WAL-G or WAL-E via Spilo
- Preload libraries: bg_mon, pg_stat_statements, pgextwlist, pg_auth_mon
- Incl. popular Postgres extensions such as decoderbufs, hypopg, pg_cron, pg_repack, pg_partman, pg_stat_kcache, pg_audit, pgfaceting, pgq, pgvector, plpgsql_check, plproxy, postgis, roaringbitmap, set_user and timescaledb
The Postgres Operator has been developed at Zalando and is being used in production for over five years.
