If the PAGER environment variable is set but contains an empty string,
psql would pass it to "sh" which would silently exit, causing whatever
query output we were printing to vanish entirely. This is quite
mystifying; it took a long time for us to figure out that this was the
cause of Joseph Brenner's trouble report. Rather than allowing that
to happen, we should treat this as another way to specify "no pager".
(We could alternatively treat it as selecting the default pager, but
it seems more likely that the former is what the user meant to achieve
by setting PAGER this way.)
Nonempty, but all-white-space, PAGER values have the same behavior, and
it's pretty easy to test for that, so let's handle that case the same way.
Most other cases of faulty PAGER values will result in the shell printing
some kind of complaint to stderr, which should be enough to diagnose the
problem, so we don't need to work harder than this. (Note that there's
been an intentional decision not to be very chatty about apparent failure
returns from the pager process, since that may happen if, eg, the user
quits the pager with control-C or some such. I'd just as soon not start
splitting hairs about which exit codes might merit making our own report.)
libpq's old PQprint() function was already on board with ignoring empty
PAGER values, but for consistency, make it ignore all-white-space values
as well.
It's been like this a long time, so back-patch to all supported branches.

Backpatch certain files through 9.1

Backpatch certain files through 9.0

Update all files in head, and files COPYRIGHT and legal.sgml in all back
branches.

This is the first run of the Perl-based pgindent script. Also update
pgindent instructions.

We had two copies of this function in the backend and libpq, which was
already pretty bogus, but it turns out that we need it in some other
programs that don't use libpq (such as pg_test_fsync). So put it where
it probably should have been all along. The signal-mask-initialization
support in src/backend/libpq/pqsignal.c stays where it is, though, since
we only need that in the backend.

This bug goes back to the original Postgres95 sources. Its significance
to modern PG versions is marginal, since we have not used PQprintTuples()
internally in a very long time, and it doesn't seem to have ever been
documented either. Still, it *is* exposed to client apps, so somebody
out there might possibly be using it.

Fully update git head, and update back branches in ./COPYRIGHT and
legal.sgml files.

In some hopeless situations, certain library functions in libpq and
libpgport quit the program. Use abort() for that instead of exit(),
so we don't interfere with the normal exit codes the program might
use, we clearly signal the abnormal termination, and the caller has a
chance of catching the termination.
This was originally pointed out by Debian's Lintian program.

Windows. The test itself is bypassed in configure as discussed, and
libpq has been updated appropriately to allow it to build in thread-safe
mode.

patch adds missing checks to the call sites of malloc(), strdup(),
PQmakeEmptyPGresult(), pqResultAlloc(), and pqResultStrdup(), and updates
the documentation. Per original report from Volkan Yazici about
PQmakeEmptyPGresult() not checking for malloc() failure.

macros around strings that were missing them.

Also performed an initial run through of upgrading our Copyright date to
extend to 2005 ... first run here was very simple ... change everything
where: grep 1996-2004 && the word 'Copyright' ... scanned through the
generated list with 'less' first, and after, to make sure that I only
picked up the right entries ...

handling in SIGPIPE processing; avoid unnecessary pollution of application
link-symbol namespace; spell 'pointer to function' in the conventional
way.

calling applications. This is done by blocking sigpipe in the libpq
thread and using sigpending/sigwait to possibily discard any sigpipe we
generated.

malloc() doesn't set errno, so most uses were buggy anyway.

global variables are problematic on this platform. Simplest solution
seems to be to initialize pthread key variable to 0. Also, rename this
variable and check_sigpipe_handler to something involving "pq" to
avoid gratuitous pollution of application namespace.

* removed a few redundant defines
* get_user_name safe under win32
* rationalized pipe read EOF for win32 (UPDATED PATCH USED)
* changed all backend instances of sleep() to pg_usleep
- except for the SLEEP_ON_ASSERT in assert.c, as it would exceed a
32-bit long [Note to patcher: If a SLEEP_ON_ASSERT of 2000 seconds is
acceptable, please replace with pg_usleep(2000000000L)]
I added a comment to that part of the code:
/*
* It would be nice to use pg_usleep() here, but only does 2000 sec
* or 33 minutes, which seems too short.
*/
sleep(1000000);

ignore SIGPIPE from send() in libpq, but terminate on any other SIGPIPE,
unless the user installs their own signal handler.
This is a minor fix because the only time you get SIGPIPE from libpq's
send() is when the backend dies.

client
utilities (libpq.dll and psql.exe) for win32 (missing defines,
adjustments to
includes, pedantic casting, non-existent functions) per:
http://developer.postgresql.org/docs/postgres/install-win32.html.
It compiles cleanly under Windows 2000 using Visual Studio .net. Also
compiles clean and passes all regression tests (regular and contrib)
under Linux.
In addition to a review by the usual suspects, it would be very
desirable for someone well versed in the peculiarities of win32 to take
a look.
