This strikes me as a really bad idea --- you save little space by
reducing it from the default, and open yourself up to unexpected failures.

That is almost certainly way more than you need.

People have already told you that one's a bad idea.

I'm unconvinced that setting this nonzero is a good idea. Have you done
experiments to prove that you get a benefit?

This is the cause of the bizarre-looking cost estimates. I don't
recommend setting it false as a system-wide setting. If you want
to nudge the planner towards indexscans, reducing random_page_cost
a little is probably a better way.
