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.

  This would allow creation of partitioned tables without requiring

  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
a consistent and official way.
