No- that's what setting it to "off" means, in actuality we just make it really expensive to encourage the planner to try and find another plan. That's not always possible to do though, hence the resulting plan with a really high cost. The enable_* options are really just for poking around and not something you'd want to set. Thanks, Stephen
