commit will also add, to an extent, which versions of each
software component are included with the PostgreSQL Operator.

 The Crunchy PostgreSQL Operator extends Kubernetes to provide a higher-level abstraction for rapid creation and management of PostgreSQL clusters.  The Crunchy PostgreSQL Operator leverages a Kubernetes concept referred to as "[Custom Resources](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/)” to create several [custom resource definitions (CRDs)](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/#customresourcedefinitions) that allow for the management of PostgreSQL clusters.
