Planner settings like enable_indexscan used to just add a large number
(disable_cost) to the estimated plan node costs. It's a bit more
sophisticated in PG17. But in any case, I imagine "disabling an index"
could use the same mechanism. Or maybe not, maybe the setting would
just completely ignore the index.
