CloudNativePG (CNPG), originally built by EDB and now a CNCF Sandbox project, represents a paradigm shift in how PostgreSQL is managed within Kubernetes environments. Unlike traditional approaches that treat containers as mere virtual machines, CNPG is an open-source operator designed specifically for the Kubernetes API, treating the database as a critical capability of the cloud-native ecosystem. By automating the full lifecycle—from high availability failover and point-in-time recovery to native Prometheus-based observability—CNPG eliminates the operational friction typically associated with running stateful workloads at scale.
