I notice that there isn't a parameter called enable_indexonly (or similar).
ISTM that such a major new feature should be controlled by a planner

This will help us evaluate index only scans in production, and turn

It already exists and is called "enable_indexonlyscan".
Hmm. Forgive me, I pressed the wrong button and looked at current docs

Maybe we should have the stylesheet watermark the dev docs pages.
