I see posts like this a lot, and it makes me wonder what the heck you were using Kafka for that Postgres could handle, yet you had dozens of clusters? I question if you actually ever used Kafka or just operated it? Sure anyone can follow the "build a queue on a database pattern" but it falls over at the throughputs that justify Kafka. If you have a bunch of trivial 10tps workloads, of course a distributed system is overkill.

They didn’t say that the Kafka clusters they personally ran could have been handled with Postgres instead.

They first gave their credentials by mentioning their experience.

Then they basically said ”given what I know about Kafka, with my experience, I require other people who ask for it to show me that they really need it before I accommodate them - often a beefy Postgres is enough”.
