doesn't define such an account using the YAML definition provided by this
option. If not defined, a simple definition that contains only the name will

On Postgres cluster creation the operator tries to create the service account
for the Postgres pods if it does not exist in the namespace. The internal
default service account definition (defines only the name) can be overwritten
with this parameter. Make sure to provide a valid YAML or JSON string. The
default is empty.
* **pod_service_account_role_binding_definition**
This definition must bind pod service account to a role with permission
sufficient for the pods to start and for Patroni to access K8s endpoints;

account to the operator's own 'zalando-postgres-operator' cluster role will
be used. The default is empty.
