3892dc75eb Add URLs for:
* 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.  Options could include range and hash
  partition selection.

2f2b58d642 Spit items:
* 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.

8426b5640e Update TODO description:
* 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.
