      * Experiment with multi-threaded backend better I/O utilization
      
        This would allow a single query to make use of multiple I/O channels
        simultaneously.  One idea is to create a background reader that can
        pre-fetch sequential and index scan pages needed by other backends.
        This could be expanded to allow concurrent reads from multiple devices
        in a partitioned table.
      
      * Experiment with multi-threaded backend better CPU utilization
      
        This would allow several CPUs to be used for a single query, such as
        for sorting or query execution.

      * Speed WAL recovery by allowing more than one page to be prefetched
      
        This should be done utilizing the same infrastructure used for
        prefetching in general to avoid introducing complex error-prone code
        in WAL replay.
