Your blog doesn't really mention any of the turn key PostgreSQL deployment options out there. These days, especially on Kubernetes, it has never been easier to run a SaaS-equivalent PostgreSQL stack.

I think you may benefit from researching the ecosystem some more.

The author seems to have spent the better part of a decade working professionally with Postgres. I think editorial choice, rather than ignorance, might be why they’re not mentioning more prior art.

Yes. :) We quite like k8s-based managed Postgres solutions. In fact, we convinced Patroni's author to come work with us in a previous gig at Microsoft. We find that a good number of companies successfully use k8s to manage Postgres for themselves.

In this blog post, we wanted to focus on running Postgres for others. AWS, Azure, and GCP's managed Postgres services, and those offered by startups like Crunchy, don't use k8s-based solutions. For us, one reason was operational simplicity. You can write a control plane for managed Postgres in 20K lines of code, including unit tests. This way, if anything breaks at scale, you can quickly figure out the issue without having to dive into dependencies.

We also understand different tradeoffs apply when you're running Postgres for yourself or for others. In this blog post, we wanted to focus on the latter scenario.

I'm not sure if 20k lines of code and and writing a controller on k8s are really that incompatible. kubebuilder has made it pretty approachable.

Being critical without posting actual better solutions isn't so helpful.

If you have concrete knowledge, please share it and don't be cryptic!
