a0fad9762a Re-implement division for numeric values using the traditional "schoolbook" 
algorithm.  This is a good deal slower than our old roundoff-error-prone
code for long inputs, so we keep the old code for use in the transcendental
functions, where everything is approximate anyway.  Also create a
user-accessible function div(numeric, numeric) to provide access to the
exact result of trunc(x/y) --- since the regular numeric / operator will
round off its result, simply computing that expression in SQL doesn't
reliably give the desired answer.  This fixes bug #3387 and various related
corner cases, and improves the usefulness of PG for high-precision integer
arithmetic.

55f6e5f689 Add a variant of the Levenshtein string-distance function that lets the user 
specify the cost values to use, instead of always using 1's.

In passing, remove fuzzystrmatch.h, which contained a bunch of stuff that had
no business being in a .h file; fold it into its only user, fuzzystrmatch.c.

d5466e38f0 Add SPI-level support for executing SQL commands with one-time-use plans, 
that is commands that have out-of-line parameters but the plan is prepared
assuming that the parameter values are constants.  This is needed for the
plpgsql EXECUTE USING patch, but will probably have use elsewhere.

This commit includes the SPI functions and documentation, but no callers
nor regression tests.  The upcoming EXECUTE USING patch will provide
regression-test coverage.  I thought committing this separately made
sense since it's logically a distinct feature.

3405f2b925 Use error message wordings for permissions checks on .pgpass and SSL private 
key files that are similar to the one for the postmaster's data directory
permissions check.  (I chose to standardize on that one since it's the most
heavily used and presumably best-wordsmithed by now.)  Also eliminate explicit
tests on file ownership in these places, since the ensuing read attempt must
fail anyway if it's wrong, and there seems no value in issuing the same error
message for distinct problems.  (But I left in the explicit ownership test in
postmaster.c, since it had its own error message anyway.)  Also be more
specific in the documentation's descriptions of these checks.  Per a gripe
from Kevin Hunter.

2169e42bef Enable 64-bit integer datetimes by default, per previous discussion. 
This requires a working 64-bit integer type. If such a type cannot
be found, "--disable-integer-datetimes" can be used to switch
back to the previous floating point-based datetime implementation.

220db7ccd8 Simplify and standardize conversions between TEXT datums and ordinary C 
strings.  This patch introduces four support functions cstring_to_text,
cstring_to_text_with_len, text_to_cstring, and text_to_cstring_buffer, and
two macros CStringGetTextDatum and TextDatumGetCString.  A number of
existing macros that provided variants on these themes were removed.

Most of the places that need to make such conversions now require just one
function or macro call, in place of the multiple notational layers that used
to be needed.  There are no longer any direct calls of textout or textin,
and we got most of the places that were using handmade conversions via
memcpy (there may be a few still lurking, though).

This commit doesn't make any serious effort to eliminate transient memory
leaks caused by detoasting toasted text objects before they reach
text_to_cstring.  We changed PG_GETARG_TEXT_P to PG_GETARG_TEXT_PP in a few
places where it was easy, but much more could be done.

05fc744b96 Add a new ereport auxiliary function errdetail_log(), which works the same as 
errdetail except the string goes only to the server log, replacing the normal
errdetail there.  This provides a reasonably clean way of dealing with error
details that are too security-sensitive or too bulky to send to the client.

This commit just adds the infrastructure --- actual uses to follow.

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.

d287818eb5 Adjust pgstatindex() to give correct answers for indexes larger than 
2^31 blocks.  Also fix pg_relpages() for the same case.

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.

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.
