> If there are many guideposts, performance will suffer during query 
> compilation because we do a linear search of the guideposts to find the 
> intersection with the scan ranges. Instead, in 
> BaseResultIterators.getParallelScans() we should populate an array of 
> guideposts and perform a binary search.
