kernel maintainers are pushing the fix burden onto PostgreSQL

Maybe it isn't applicable in this context, but didn't Linus Torvalds send an angry email on an adjacent topic, but regarding the same philosophy?

Found it: we do not break userspace

Regardless of Linus's philosophy, such a change in Postgresql would need to be backported to previous versions, because migrating from one major release to another is far from being straightforward.
