* Simplify ability to create partitioned tables This would allow creation of partitioned tables without requiring creation of triggers or rules for INSERT/UPDATE/DELETE, and constraints for rapid partition selection.

* 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.
