The watched namespace also needs to have a (possibly different) service account
in the case database pods need to talk to the K8s API (e.g. when using
K8s-native configuration of Patroni). The operator checks that the
`pod_service_account_name` exists in the target namespace, and, if not, deploys
there the `pod_service_account_definition` from the operator
[`Config`](../pkg/util/config/config.go) with the default value of:
```yaml

In this definition, the operator overwrites the account's name to match
`pod_service_account_name` and the `default` namespace to match the target
namespace. The operator performs **no** further syncing of this account.

### Service account and cluster roles
### Namespaced service account and role binding
Note that the service account is named `zalando-postgres-operator`. You may have
to change the `service_account_name` in the operator ConfigMap and
`serviceAccountName` in the `postgres-operator` deployment appropriately. This
is done intentionally to avoid breaking those setups that already work with the
default `operator` account. In the future the operator should ideally be run
under the `zalando-postgres-operator` service account.
For each namespace the operator watches it creates (or reads) a service account
and role binding to be used by the Postgres Pods. The service account is bound
to the `postgres-pod` cluster role. The name and definitions of these resources
can be [configured](reference/operator_parameters.md#kubernetes-resources).
Note, that the operator performs **no** further syncing of namespaced service
accounts and role bindings.
