We've started using CNPG cautiously in production and can say we're finally confident about running databases in kubernetes. (we had a bad run before with custom setups, and went back to using VMs again).

I am very grateful to maintainers for not only open sourcing the industrial-grade operator, but also sharing so much of their expertise. Unexpected side-effect of adopting CNPG for us was that we now have a good starting point for running postgres with high availability. (obvs there's still a lot to learn, but CNPG docs is a treasure trove of operational knowledge)
