0ffc201a51 Add file version information to most installed Windows binaries.
Prominent binaries already had this metadata.  A handful of minor
binaries, such as pg_regress.exe, still lack it; efforts to eliminate
such exceptions are welcome.

6f03927fce Properly check for readdir/closedir() failures
Clear errno before calling readdir() and handle old MinGW errno bug
while adding full test coverage for readdir/closedir failures.

Backpatch through 8.4.

01824385ae Prevent potential overruns of fixed-size buffers.
Coverity identified a number of places in which it couldn't prove that a
string being copied into a fixed-size buffer would fit.  We believe that
most, perhaps all of these are in fact safe, or are copying data that is
coming from a trusted source so that any overrun is not really a security
issue.  Nonetheless it seems prudent to forestall any risk by using
strlcpy() and similar functions.

Fixes by Peter Eisentraut and Jozef Mlich based on Coverity reports.

In addition, fix a potential null-pointer-dereference crash in
contrib/chkpass.  The crypt(3) function is defined to return NULL on
failure, but chkpass.c didn't check for that before using the result.
The main practical case in which this could be an issue is if libc is
configured to refuse to execute unapproved hashing algorithms (e.g.,
"FIPS mode").  This ideally should've been a separate commit, but
since it touches code adjacent to one of the buffer overrun changes,
I included it in this commit to avoid last-minute merge issues.
This issue was reported by Honza Horak.

Security: CVE-2014-0065 for buffer overruns, CVE-2014-0066 for crypt()

60ff2fdd99 Centralize getopt-related declarations in a new header file pg_getopt.h.
We used to have externs for getopt() and its API variables scattered
all over the place.  Now that we find we're going to need to tweak the
variable declarations for Cygwin, it seems like a good idea to have
just one place to tweak.

In this commit, the variables are declared "#ifndef HAVE_GETOPT_H".
That may or may not work everywhere, but we'll soon find out.

3c07fbf40b Use pqsignal() in contrib programs rather than calling signal(2) directly.
The semantics of signal(2) are more variable than one could wish; in
particular, on strict-POSIX platforms the signal handler will be reset
to SIG_DFL when the signal is delivered.  This demonstrably breaks
pg_test_fsync's use of SIGALRM.  The other changes I made are not
absolutely necessary today, because the called handlers all exit the
program anyway.  But it seems like a good general practice to use
pqsignal() exclusively in Postgres code, now that we have it available
everywhere.

bb7520cc26 Make documentation of --help and --version options more consistent
Before, some places didn't document the short options (-? and -V),
some documented both, some documented nothing, and they were listed in
various orders.  Now this is hopefully more consistent and complete.

48912acc08 Disable triggering failover with a signal in pg_standby on Windows, because
Windows doesn't do signal processing like other platforms do. It never
really worked, but recent changes to the signal handling made it crash.

8fd733bd19 Disable pg_standby -l option because the backend doesn't expect the recovered
file to be a symlink. We tried to fix this issue with an earlier server-side
patch, but it didn't fix the whole issue.

The same bug is present in older releases as well, but the 8.4 train is
about to leave the station, and I'm not sure if have consensus on whether
we can remove the -l option in back-branches or do we need to attempt a
server-side fix to make symlinking safe.

Patch by Simon Riggs, per discussion on bug identified by Fujii Masao.

9e403c2587 Add recovery_end_command option to recovery.conf. recovery_end_command
is run at the end of archive recovery, providing a chance to do external
cleanup. Modify pg_standby so that it no longer removes the trigger file,
that is to be done using the recovery_end_command now.

Provide a "smart" failover mode in pg_standby, where we don't fail over
immediately, but only after recovering all unapplied WAL from the archive.
That gives you zero data loss assuming all WAL was archived before
failover, which is what most users of pg_standby actually want.

recovery_end_command by Simon Riggs, pg_standby changes by Fujii Masao and
myself.

753a040486 Don't set the signal handler for SIGQUIT on Windows. Buildfarm shows that
reinstalling the default signal handler doesn't work as it is on Windows.
Presumably core dumps on SIGQUIT are not a problem on Windows, so rather
than figure out what header files or other changes are required to make it
work, just don't bother.

53972b460c Add $PostgreSQL$ markers to a lot of files that were missing them.
This particular batch was just for *.c and *.h file.

The changes were made with the following 2 commands:

find . \( \( -name 'libstemmer' -o -name 'expected' -o -name 'ppport.h' \) -prune \) -o  \( -name '*.[ch]'  \) \( -exec grep -q '\$PostgreSQL' {} \; -o -print \) | while read file ; do head -n 1 < $file | grep -q '^/\*' && echo $file; done | xargs -l sed -i -e '1s/^\// /' -e '1i/*\n * $PostgreSQL:$ \n *'

find . \( \( -name 'libstemmer' -o -name 'expected' -o -name 'ppport.h' \) -prune \) -o  \( -name '*.[ch]'  \) \( -exec grep -q '\$PostgreSQL' {} \; -o -print \) | xargs -l sed -i -e '1i/*\n * $PostgreSQL:$ \n */'

f0eb3e5e58 Fix incorrect archive truncation point calculation in the %r recovery_command
parameter. This fixes bug 4137 reported by Wojciech Strzalka, where a WAL
file is deleted too early when starting the recovery of a warm standby server.

Also add a sanity check in pg_standby so that it will refuse to delete anything
earlier than the file being restored, and improve the debug message in case
nothing is deleted.

Simon Riggs. Backpatch to 8.3, which is where %r was introduced.

f18dfc4835 Minor improvements in backup and recovery:
- create a separate archive_mode GUC, on which archive_command is dependent

- %r option in recovery.conf sends last restartpoint to recovery command

- %r used in pg_standby, updated README

- minor other code cleanup in pg_standby

- doc on Warm Standby now mentions pg_standby and %r

- log_restartpoints recovery option emits LOG message at each restartpoint

- end of recovery now displays last transaction end time, as requested
  by Warren Little; also shown at each restartpoint

- restart archiver if needed to carry away WAL files at shutdown
