Operators are useful in building an orchestration layer on top of a container platform such as Kubernetes. Orchestration features such as backup, restore, cloning, and upgrades will be highlighted. An operator is an extension of a cloud based PostgreSQL deployment and would be of interest to companies deploying PostgreSQL on cloud environments.
