* Protected and system users can't be a connection pool user It's not supported, neither it's a best practice. Also fix potential null pointer access. For protected users it makes sense by intent of protecting this users (e.g. from being overriden or used as something else than supposed). For system users the reason is the same as for superuser, it's about replicastion user and it's under patroni control. This is implemented on both levels, operator config and postgresql manifest. For the latter we just use default name in this case, assuming that operator config is always correct. For the former, since it's a serious misconfiguration, operator panics. |

Postgres Operator
The Postgres Operator enables highly-available PostgreSQL clusters on Kubernetes (K8s) powered by Patroni. It is configured only through manifests to ease integration into automated CI/CD pipelines with no access to Kubernetes directly.
Operator features
- Rolling updates on Postgres cluster changes
- Volume resize without Pod restarts
- Database connection pooler
- Cloning Postgres clusters
- Logical backups to S3 Bucket
- Standby cluster from S3 WAL archive
- Configurable for non-cloud environments
- UI to create and edit Postgres cluster manifests
PostgreSQL features
- Supports PostgreSQL 9.6+
- Streaming replication cluster via Patroni
- Point-In-Time-Recovery with pg_basebackup / 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_partman, pg_stat_kcache, pgq, plpgsql_check, postgis, set_user and timescaledb
The Postgres Operator has been developed at Zalando and is being used in production for over two years.
