Before we run the query, we need to add pager-based range() instructions to it.

- Query extender for pager queries.
Code
public function execute() {
// Add convenience tag to mark that this is an extended query. We have to
// do this in the constructor to ensure that it is set before preExecute()
// gets called.
if (!$this->preExecute($this)) {

}
// A NULL limit is the "kill switch" for pager queries.

// Now that we've added our pager-based range instructions, run the query normally.
