Just a heads up, we were using the bitnami charts in our first attempt at an HA postgres instance in our k8s cluster, and we're currently figuring out how to move away from them because they had so many issues.
Granted, we might've messed something up and there are lots of factors, but you should manually check your individual nodes every so often to make sure none of them are going out of sync. Need to connect to each one directly, can't rely on what the bouncer/pgpool/loadbalancer is showing you to check the data is the same. It happened repeatedly to us, and wasn't obvious from any of our monitoring. In the end we had to scale down to 1 node while we sort out moving to a different operator.
I think the allure comes from solving a very sharp pain point if you're a hobbyist developer or new to mobile dev: push notifications.
I don't know about others, but the first time I looked into apps, I could make sense of everything until I got to push notifications. Then it became this insanely complicated rabbit hole with a bunch of companies saying they'd solve it for you for 20 bucks a month or whatever. For something that on the surface sounds like it should be dead simple.
So a simple, clean, free way to send a push notification to your phone, that you can use with a web request from anywhere? I can definitely see the mass appeal of that to the millions of people with small projects who don't want to become experts on google/apple's ecosystems just to make some words pop up on their phone.
