Create DB and Users at start

Hi

I am using pg-db and pg-operator and installing using helm but what i want is i need to create few database and users at start

I saw the options in values.yaml

users:

  • name: pg
    databases:
    • zoo
      options: “SUPERUSER”
      password:
      type: ASCII
      secretName: “rhino-credentials”

databaseInitSQL:
key: init.sql
name: cluster1-init-sql

But it is not working

Guide me the correct way to create database and users at start
