```

Note that the Kubernetes version 1.13 brings [taint-based eviction](https://kubernetes.io/docs/concepts/configuration/taint-and-toleration/#taint-based-evictions) to the beta stage and enables it by default.
Postgres pods by default receive tolerations for `unreachable` and `noExecute` taints with the timeout of `5m`.
Depending on your setup, you may want to adjust these parameters to prevent master pods from being evicted by the Kubernetes runtime.
To prevent eviction completely, specify the toleration by leaving out the `tolerationSeconds` value (similar to how Kubernetes' own DaemonSets are configured)

### Enable pod anti affinity

To ensure Postgres pods are running on different topologies, you can use [pod anti affinity](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/)
