Continuing 63f32f3416a8b4f8e057dc184e8e8eae734ccc8a, libpgcommon should
depend on libpgport, but not vice versa. But wait_result_to_str() in
wait_error.c depends on pstrdup() in libpgcommon. So move exec.c and
wait_error.c from libpgport to libpgcommon. Also switch the link order
in the place that's actually used by the failing ecpg builds.
The function declarations have been left in port.h for now. That should
perhaps be separated sometime.
Commit 95ef6a344821655ce4d0a74999ac49dd6af6d342 removed the
ability to create rules on an individual column as of 7.3, but
left some residual code which has since been useless. This cleans
up that dead code without any change in behavior other than
dropping the useless column from the catalog.
Update emacs.samples with new configuration snippets that match pgindent
et al. formatting more accurately and follow Emacs Lisp best practices
better.
Add .dir-locals.el with a subset of that configuration for casual
editing and viewing.

Treat TOAST index just the same as normal one and get the OID

This change allows us to handle multiple TOAST indexes, and

Valgrind "client requests" in aset.c and mcxt.c teach Valgrind and its
Memcheck tool about the PostgreSQL allocator. This makes Valgrind
roughly as sensitive to memory errors involving palloc chunks as it is
to memory errors involving malloc chunks. Further client requests in
PageAddItem() and printtup() verify that all bits being added to a
buffer page or furnished to an output function are predictably-defined.
Those tests catch failures of C-language functions to fully initialize
the bits of a Datum, which in turn stymie optimizations that rely on
_equalConst(). Define the USE_VALGRIND symbol in pg_config_manual.h to
enable these additions. An included "suppression file" silences nominal
errors we don't plan to fix.

New infrastructure is added which creates a set number of workers
(threads on Windows, forked processes on Unix). Jobs are then
handed out to these workers by the master process as needed.
pg_restore is adjusted to use this new infrastructure in place of the
old setup which created a new worker for each step on the fly. Parallel
dumps acquire a snapshot clone in order to stay consistent, if
available.
The parallel option is selected by the -j / --jobs command line
parameter of pg_dump.

This appears to cause some intermittent file system problems
on Windows 8. Instead, set up the old data directory in its
intended final location to start with.
I had thought we weren't using this version of pqsignal() at all on
Windows, but that's wrong --- initdb is using it (and coping with the
POSIX-ish semantics of bare signal() :-(). So allow the file to be
built in WIN32+FRONTEND case, and add it to the MSVC build logic.
The previous commit didn't work on MSVC editions earlier than
Visual Studio 2011, apparently. This works by copying files into the
contrib directory, and making provision to clean them up, which should
work on all editions.
This enables non-backend code, such as pg_xlogdump, to use it easily.
The previous location, in src/backend/catalog/catalog.c, made that
essentially impossible because that file depends on many backend-only
facilities; so this needs to live separately.
The previous order of steps didn't literally work, because git clean
-fdx would delete the downloaded typedefs.list. Also, pgindent needs to
be called with a path when one is in at the top of the build tree.
libpgcommon is a new static library to allow sharing code among the
various frontend programs and backend; this lets us eliminate duplicate
implementations of common routines. We avoid libpgport, because that's
intended as a place for porting issues; per discussion, it seems better
to keep them separate.
The first use case, and the only implemented by this patch, is pg_malloc
and friends, which many frontend programs were already using.
At the same time, we can use this to provide palloc emulation functions
for the frontend; this way, some palloc-using files in the backend can
also be used by the frontend cleanly. To do this, we change palloc() in
the backend to be a function instead of a macro on top of
MemoryContextAlloc(). This was previously believed to cause loss of
performance, but this implementation has been tweaked by Tom and Andres
so that on modern compilers it provides a slight improvement over the
previous one.
This lets us clean up some places that were already with
localized hacks.
Most of the pg_malloc/palloc changes in this patch were authored by
Andres Freund. Zoltán Böszörményi also independently provided a form of
that. libpgcommon infrastructure was authored by Álvaro.
This ensure the version number increases over time. The first three digits
in the version number is still set to the actual PostgreSQL version
number, but the last one is intended to be an ever increasing build number,
which previosly failed when it changed between 1, 2 and 3 digits long values.

Get rid of the fundamentally indefensible assumption that "long long int"
exists and is exactly 64 bits wide on every platform Postgres runs on.
Instead let the configure script select the type to use for "pg_int64".
This is a bit of a pain in the rear since we do not want to pollute client
namespace with all the random symbols that pg_config.h defines; instead
we have to create a separate generated header file, "pg_config_ext.h".
But now that the infrastructure is there, we might have the ability to
add some other stuff that's long been wanting in this area.
This makes the naming inside plpgsql consistent and distinguishes the
file from the backend's gram.y file. It will also allow easier
refactoring of the bison make rules later on.
This script is a bit slow, but still it only takes a fraction of the time
the bison run does, so the overhead doesn't seem intolerable. And we
definitely need some mechanical aid here, because people keep missing
the need to add new keywords to the appropriate keyword-list production.
While at it, I moved check_keywords.pl from src/tools into
src/backend/parser where it's actually used, and did some very minor
cleanup on the script.
