You seem to be under the illusion that "stable" is a control knob for a
function result cache. It is not, and never has been. Postgres doesn't
do function result caching.
If you've constructed your app in such a way that it depends on not
inlining SQL set-returning functions, it's fairly easy to defeat that.

(although volatile might cause you problems elsewhere --- I suspect
your design is pretty brittle in this area).
