This is a kubernetes or postgres-operator bug (setting up the wrong cgroup
limit, which the docs explicitly warn against doing). I don't think we want to
accumulate workarounds like that in postgres.

Huh. I don't know anything about the controller, but that seems problematic
independent of this specific issue. And you'd still need to deploy a new
version of postgres to get such changes...
