Vanilla MySQL vs vanilla Postgres. MySQL still wins on scale. You run single MySQL servers with 70,000 connections, you can't get close on Postgres because of a fundamentally broken connection-per-process model. The Neon team suggested changing that and got flamed by the community.
I was at GitHub in 2017 when that GitLab outage happened. We had 60 million users running on vanilla MySQL no Vitess at that point. We had 10 million users literally running on 3 MySQL servers. Don't pretend that even now Postgres can do that.
