This tool makes it possible to do the pg_start_backup/
copy files/pg_stop_backup step in a single command.

There are still some steps to be done before this is a
complete backup solution, such as the ability to stream
the required WAL logs, but it's still usable, and
could do with some buildfarm coverage.

In passing, make the checkpoint request optionally
fast instead of hardcoding it.

Makes it easier to parse mainly the BASE_BACKUP command
with it's options, and avoids having to manually deal
with quoted identifiers in the label (previously broken),
and makes it easier to add new commands and options in
the future.

In passing, refactor the case statement in the walsender
to put each command in it's own function.

Forgot this with previuos commit, line it up so it's easier to
submit (readable) patches against the MSVC build system.

wait until it is set. Latches can be used to reliably wait until a signal
arrives, which is hard otherwise because signals don't interrupt select()
on some platforms, and even when they do, there's race conditions.

On Unix, latches use the so called self-pipe trick under the covers to
implement the sleep until the latch is set, without race conditions. On
Windows, Windows events are used.

Use the new latch abstraction to sleep in walsender, so that as soon as
a transaction finishes, walsender is woken up to immediately send the WAL
to the standby. This reduces the latency between master and standby, which
is good.

helpful comments from many people.

directly.  This was a lot of trouble, but should be worth it in terms of
not having to keep the plpgsql lexer in step with core anymore.  In addition
the handling of keywords is significantly better-structured, allowing us to
de-reserve a number of words that plpgsql formerly treated as reserved.

Test coverage support now covers the entire source tree, including
contrib, instead of just src/backend.  In a related but independent
development, the commands make coverage and make coverage-html can be run
in any directory.

This turned out to be much easier than feared.  Besides a few ad hoc fixes
to pass the make target down the tree, change all affected makefiles to
list their directories in the SUBDIRS variable, changed from variants like
DIRS and WANTED_DIRS.  MSVC build fix was attempted as well.

and extend configure to test for it properly instead of hard-wiring
an assumption that everybody but Windows has the rand48 functions.
(We do cheat to the extent of assuming that probing for erand48 will do
for the entire rand48 family.)

erand48() is unused as of this commit, but a followon patch will cause
GEQO to depend on it.

We should probably have a better way to do this (meaning
something not hardcoded) eventually, but this fixes the
problem for 8.4.

been removed. This should unbreak the msvc build again.

Also, if linked against other versions than the default MSVCRT library
(for example the MSVC build which links against MSVCRT80), also update
the cache in the default MSVCRT at the same time.

This should fix the issues with setting LC_MESSAGES on the MSVC build.

subdomains.

Since this means we no longer need fnmatch, remove the imported implementation
from port, along with the autoconf check for it.

This uses the function fnmatch() which is not available on all platforms
(notably Windows), so import the implementation from NetBSD into src/port.

since it's now just a SQL module and no C code.

Use #define/#ifdef instead of sed to fix include files, this should work on Windows too.
