Operating a reliable Postgres service is an entirely different set of technologies, expertise, and resources than just the software itself. AWS doesn’t make money off of the Postgres code. They make money off of providing a reliable and hands-off Postgres hosting system that includes compute, security, scaling, backups, and upgrades. The Postgres code itself is only a small part of the work and resources that go into providing such a service. Your dismissive attitude for the expertise and resources that go into quality system operation is really depressing.
