### AI overview

A tutorial demonstrates resizing, scaling, and minor version upgrades for PostgreSQL running on Kubernetes with the CYBERTEC PG Operator. Using end-to-end minikube tests, it shows declarative manifest changes, rolling updates, Patroni failover, and scaling while the cluster remains available.

### AI overview

This tutorial demonstrates how to deploy a highly available PostgreSQL cluster on Kubernetes with the CYBERTEC PG Operator. Using a 14-line YAML configuration on minikube, it shows leader election, streaming replication, health checks, automatic failover, and read-only replica behavior. It also explains how anti-affinity must be disabled for the single-node minikube setup but should remain enabled on multi-node production clusters.
