7de81124d5 Create a function quote_nullable(), which works the same as quote_literal()
except that it returns the string 'NULL', rather than a SQL null, when called
with a null argument.  This is often a much more useful behavior for
constructing dynamic queries.  Add more discussion to the documentation
about how to use these functions.

* 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.

6b0706ac33 Arrange for an explicit cast applied to an ARRAY[] constructor to be applied
directly to all the member expressions, instead of the previous implementation
where the ARRAY[] constructor would infer a common element type and then we'd
coerce the finished array after the fact.  This has a number of benefits,
one being that we can allow an empty ARRAY[] construct so long as its
element type is specified by such a cast.

Brendan Jurd, minor fixes by me.

68528d37bb Support a --no-tablespaces option in pg_dump/pg_dumpall/pg_restore, so that
dumps can be loaded into databases without the same tablespaces that the
source had.  The option acts by suppressing all "SET default_tablespace"
commands, and also CREATE TABLESPACE commands in pg_dumpall's case.

Gavin Roy, with documentation and minor fixes by me.

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.

errors in any commands, including in various clean targets that have so far
been handled inconsistently.  make -i is available to ignore all errors in
