assigns the `nodeAffinity` clause to the Postgres pods to be scheduled only
on `ready` nodes. If a `nodeAffinity` is specified in the postgres cluster
manifest as well the `nodeSelectorTerms` will get merged. If the
`nodeAffinity` of the manifest contains only one `matchExpressions` slice

When multiple selector expressions are defined in the manifest an extra
