how to create several clusters with different configurations.

[antverpp]

I am using zalando postgres operator. Installed operator has a postgres-pod-config.
And each new postgres cluster inherits values from this configmap, even if it is created in another namespace.
But the issue is the following.
I need to create additional postgres cluster with values, that are different from those in postgres-pod-config.
Please, suggest how can I specify for each cluster its own pod configmap ?
