SideCar question

[AlHood77]

I have the postgres exporter deployed as a sidecar in my operator config. I've just upgraded the version of the exporter and can see that new version reflected in my operator config in the cluster however all my db pods are still using the old exporter version. Is there something I'm missing in the docs that I need to do for the pods to update with the newer version? Currently using spilo-13:2.0-p6
