The Postgres Operator delivers an easy to run highly-available [PostgreSQL](https://www.postgresql.org/)
clusters on Kubernetes (K8s) powered by [Patroni](https://github.com/zalando/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.
* 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 17, starting from 13+
* Streaming replication cluster via Patroni
* Point-In-Time-Recovery with
[pg_basebackup](https://www.postgresql.org/docs/17/app-pgbasebackup.html) /
[WAL-E](https://github.com/wal-e/wal-e) via [Spilo](https://github.com/zalando/spilo)
* Preload libraries: [bg_mon](https://github.com/CyberDem0n/bg_mon),
[pg_stat_statements](https://www.postgresql.org/docs/17/pgstatstatements.html),
