I agree AWS should be contributing back to the open source projects and they are listed as a 'sponsor' (though not a major one) on the Postgres website. https://www.postgresql.org/about/policies/sponsorship/ https://www.postgresql.org/about/policies/sponsorship/ But AWS should not have to take responsibility for providing indefinite updates to every version of every managed open source project it operates. The only way I could see this working would be if AWS charged the holdouts the cost of keeping them supported. However, performing RDS Postgres upgrades is relatively quick and painless process. If a company doesn't have the capacity to do that every five years, then it shouldn't be running its own infrastructure.
