I am trying to set istio annotation for my postgresql pods but no success so far

I tried to put my annotations under expose in values yaml file which is at the root level of the values file but nothing changes. I tried to add annotation directly in cluster.yaml from the templates , still no change

I am using postgres operator chart:  
version: 2.3.5  
appVersion: 2.3.1  
Postgresql database chart:  
version: 2.3.18  
appVersion: 2.3.1  
postgresVersion: 15

@mboncalo I’m looking into it. While I’m doing it - could you please share how you use Istio? What is the main use case?
