Make ecpg in line with other compilers in that it deletes its output if there was an error processing the input file.

Work done by Zoltan.

The endterm attribute is mainly useful when the toolchain does not support
automatic link target text generation for a particular situation.  In  the
past, this was required by the man page tools for all reference page links,
but that is no longer the case, and it now actually gets in the way of
proper automatic link text generation.  The only remaining use cases are
currently xrefs to refsects.

"CREATE TEXT SEARCH CONFIGURATION" is not truncated.

reasonably promptly, by adding CHECK_FOR_INTERRUPTS in the per-page loops.

The previous coding failed in various scenarios possibly including vpath
builds and doing make install without preceding make all.

This allows us to see what mode the server is in before it starts to
perform actions that can block or hang. Otherwise server messages
may not appear until after messages that say FATAL the database
server is starting up.

corrupted. This error, however, does is not a compilation problem but a runtime
one, so we can keep compiling but still have to declare ERROR.

Windows, thanks to a feature in CRT called Parameter Validation.

Backpatch to 8.2, which is the oldest version supported on Windows. In
8.2 and 8.3 also backpatch the earlier change to use DEVNULL instead of
NULL_DEV #define for a /dev/null-like device. NULL_DEV was hard-coded to
"/dev/null" regardless of platform, which didn't work on Windows, while
DEVNULL works on all platforms. Restarting syslogger didn't work on
Windows on versions 8.3 and below because of that.

Use a file of patterns of filenames to exclude from pgindent runs, instead if using multiple invocations of egrep. Add perl ppport.h to the current list.

Zoltan beautified his hidden-variable-patch for ecpg. This also makes sure we get an error message instead of a warning if the variable have different types.

Applied Zoltan's patch to make ecpg spit out warnings if a local variable hides a global one with the same name.

The error message now makes explicit reference to the GUC that must be changed
to fix the problem, using wording suggested by Tom Lane.  Along the way,
rename the GUC from MaxWalSenders to max_wal_senders for consistency and
grep-ability.

more appropriate place for exclusion constraints.

after my other commit.

"replication" are quoted in pg_hba.conf, they lose their special meaning.

loop in standby mode, trying to restore from archive, pg_xlog and
streaming.

Move sections around to make the high availability chapter more
coherent: the most prominent part is now a "Log-Shipping Standby Servers"
section that describes what a standby server is (like the old
"Warm Standby Servers for High Availability" section), and how to
set up a warm standby server, including streaming replication, using the
built-in standby mode. The pg_standby method is desribed in another
section called "Alternative method for log shipping", with the added
caveat that it doesn't work with streaming replication.

default values, with example comments.

constraint exclusion on an inheritance set that is the target of an UPDATE
or DELETE query.  Per gripe from Marc Cousin.  Back-patch to 8.4 where
the feature was introduced.

pg_xlog directory. This is essential for replaying WAL records that
were streamed from the master, after a standby server restart.

If a corrupt record is seen in a file restored from the archive or
streamed from the master, log it as a WARNING and keep retrying. If the
corruption is permanent, and not just a glitch in the whatever copies the
files to the archive or a network error not caught by CRC checks in TCP
for example, we will keep retrying and logging the WARNING indefinitely.
But that's better than shutting down completely, the standby is still
useful for running read-only queries. In PITR the recovery ends at such a
corrupt record, which is a bit questionable, but that's the behavior we
had in previous releases and we don't feel like chaning it now. It does
make sense for tools like pg_standby.

btree_xlog_delete_get_latestRemovedXid().  This variable was only tested
in assert builds.

It is no longer installed by default, but included in "make world"/"make
install-world".  Documentation updated accordingly.

Also, fix vpathsearch function to work when calling make install-docs
without previous make docs.
