Postgres Operator
The Postgres Operator delivers an easy to run highly-available PostgreSQL clusters on Kubernetes (K8s) powered by Patroni.

- 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
