When we loop back to the top of doCustom after processing a backslash
command, we must reset the "now" timestamp, because that's used to
calculate the time spent executing the previous command.
Report and fix by Fabien Coelho. Backpatch to 9.5, where this was broken.
On Windows, use listen_address=127.0.0.1 to allow TCP connections. We were
already using "pg_regress --config-auth" to set up HBA appropriately. The
standard_initdb helper function now sets up the server's
unix_socket_directories or listen_addresses in the config file, so that
they don't need to be specified in the pg_ctl command line anymore. That
way, the pg_ctl invocations in test programs don't need to differ between
Windows and Unix.
Add another helper function to configure the server's pg_hba.conf to allow
replication connections. The configuration is done similarly to "pg_regress
--config-auth": trust on domain sockets on Unix, and SSPI authentication on
Windows.
Replace calls to "cat" and "touch" programs with built-in perl code, as
those programs don't normally exist on Windows.
Add instructions in the docs on how to install IPC::Run on Windows. Adjust
vcregress.pl to not replace PERL5LIB completely in vcregress.pl, because
otherwise cannot install IPC::Run in a non-standard location easily.

This option specifies a replication slot for WAL streaming (-X stream),
so that there can be continuous replication slot use between WAL
streaming during the base backup and the start of regular streaming
replication.

This was broken in 1bc90f7a, which removed the thread-emulation. With modest
-j and -c settings the result were usually close enough that you wouldn't
notice it easily, but with a high enough thread count it would access
uninitialized memory and crash.
Per report from Andres Freund offlist.
This was broken by commit 0e7e355f27 and
friends, which ignored the fact that gzopen() will treat "-1" in the
mode argument as an invalid character, which it ignores, and a flag for
compression level 1. Now, when this value is encountered no compression
level flag is passed to gzopen, leaving it to use the zlib default.
Also, enforce the documented allowed range for pg_dump's -Z option,
namely 0 .. 9, and remove some consequently dead code from
pg_backup_tar.c.
Problem reported by Marc Mamin.
Backpatch to 9.1, like the patch that introduced the bug.
Any error other than ENOENT is a bit suspicious here, and perhaps should
not be grounds for assuming the postmaster has failed. For the moment
though, just report it, and don't change the behavior otherwise. The
intent is mainly to try to determine why we are seeing intermittent
failures in this area on some buildfarm members.
Back-patch to 9.5 where some of these failures have happened.
The original implementation of TABLESAMPLE modeled the tablesample method
API on index access methods, which wasn't a good choice because, without
specialized DDL commands, there's no way to build an extension that can
implement a TSM. (Raw inserts into system catalogs are not an acceptable
thing to do, because we can't undo them during DROP EXTENSION, nor will
pg_upgrade behave sanely.) Instead adopt an API more like procedural
language handlers or foreign data wrappers, wherein the only SQL-level
support object needed is a single handler function identified by having
a special return type. This lets us get rid of the supporting catalog
altogether, so that no custom DDL support is needed for the feature.
Adjust the API so that it can support non-constant tablesample arguments
(the original coding assumed we could evaluate the argument expressions at
ExecInitSampleScan time, which is undesirable even if it weren't outright
unsafe), and discourage sampling methods from looking at invisible tuples.
Make sure that the BERNOULLI and SYSTEM methods are genuinely repeatable
within and across queries, as required by the SQL standard, and deal more
honestly with methods that can't support that requirement.
Make a full code-review pass over the tablesample additions, and fix
assorted bugs, omissions, infelicities, and cosmetic issues (such as
failure to put the added code stanzas in a consistent ordering).
Improve EXPLAIN's output of tablesample plans, too.
Back-patch to 9.5 so that we don't have to support the original API
in production.
Per Coverity (not that any of these are so non-obvious that they should not
have been caught before commit). The extent of leakage is probably minor
to unnoticeable, but a leak is a leak. Back-patch as necessary.

pg_receivexlog and pg_recvlogical error out when --create-slot is
specified and a slot with the same name already exists. In some cases,
especially with pg_receivexlog, that's rather annoying and requires
additional scripting.
Backpatch to 9.5 as slot control functions have newly been added to
pg_receivexlog, and there doesn't seem much point leaving it in a less
useful state.

Create a log file for each test run. Stdout and stderr of the test script,
as well as any subprocesses run as part of the test, are redirected to
the log file. This makes it a lot easier to debug test failures. Also print
the test output (ok 12 - ... messages) to the log file, and the command
line of any external programs executed with the system_or_bail and run_log
functions. This makes it a lot easier to debug failing tests.
Modify some of the pg_ctl and other command invocations to not use 'silent'
or 'quiet' options, and don't redirect output to /dev/null, so that you get
all the information in the log instead.
In the passing, construct some command lines in a way that works if $tempdir
contains quote-characters. I haven't systematically gone through all of
them or tested that, so I don't know if this is enough to make that work.
pg_rewind tests had a custom mechanism for creating a similar log file. Use
the new generic facility instead.
Michael Paquier and me.
POSIX does not specify the -q option, and many implementations do not
offer it. Don't bother changing the MSVC build system, because having
non-GNU diff on Windows is vanishingly unlikely. Back-patch to 9.2,
where this invocation was introduced.
The psql crash happened when no current connection existed. (The second
new check is optional given today's undocumented NULL argument handling
in PQhost() etc.) Back-patch to 9.0 (all supported versions).
SUSv2-era shells don't set the PWD variable, though anything more modern
does. In the buildfarm environment this could lead to test.sh executing
with PWD pointing to $HOME or another high-level directory, so that there
were conflicts between concurrent executions of the test in different
branch subdirectories. This appears to be the explanation for recent
intermittent failures on buildfarm members binturong and dingo (and might
well have something to do with the buildfarm script's failure to capture
log files from pg_upgrade tests, too).
To fix, just use `pwd` in place of $PWD. AFAICS test.sh is the only place
in our source tree that depended on $PWD. Back-patch to all versions
containing this script.
Per buildfarm. Thanks to Oskari Saarenmaa for diagnosing the problem.
The previous coding tried to handle possible failures when fsyncing a
tty or pipe fd by accepting EINVAL - but apparently some
platforms (windows, OSX) don't reliably return that. So instead check
whether the output fd refers to a pipe or a tty when opening it.

Backpatch to 9.4, where pg_recvlogical was added.
You can no longer use pgbench with multiple threads when compiled without
--enable-thread-safety. That's an acceptable limitation these days; it
still works fine with -j1, and all modern platforms support threads anyway.
This makes future maintenance and development of the code easier.

There were two issues here. First, if a query got stuck so that it took
e.g. 5 seconds, and progress interval was 1 second, no progress reports were
printed until the query returned. Fix so that we wake up specifically to
print the progress report. Secondly, if pgbench got stuck so that it would
nevertheless not print a progress report on time, and enough time passes
that it's already time to print the next progress report, just skip the one
that was missed. Before this patch, it would print the missed one with 0 TPS
immediately after the previous one.
Fabien Coelho. Backpatch to 9.4, where progress reports were added.
Commit de76884 changed an archive recovery so that the last WAL
segment with old timeline was renamed with suffix .partial. It should
have updated WAL-related utilities so that they can handle such
.paritial WAL files, but we forgot that.
This patch changes pg_archivecleanup so that it can clean up even
archived WAL files with .partial suffix. Also it allows us to specify
.partial WAL file name as the command-line argument "oldestkeptwalfile".
This patch also changes pg_resetxlog so that it can remove .partial
WAL files in pg_xlog directory.
pg_xlogdump cannot handle .partial WAL files. Per discussion,
we decided only to document that limitation instead of adding the fix.
Because a user can easily work around the limitation (i.e., just remove
.partial suffix from the file name) and the fix seems complicated for
very narrow use case.
Back-patch to 9.5 where the problem existed.

-t will now match views, foreign tables, materialized views, and sequences,
not only plain tables. This is more useful, and also more consistent with
the behavior of pg_dump's -t switch, which has always matched all relation
types.
We're still not there on matching pg_dump's behavior entirely, so mention
that in the docs.

There's no point in trying to free every small allocation in these
programs that are used in a one-shot fashion, but these ones seems like
an improvement on readability grounds.

Patch by David Rowley. Backpatch to 9.5, as some of the calls were new in
9.5, and keeping the code in sync with master makes future backpatching
easier.
Commit 179cdd09 added macros to check if a filename is a WAL segment
or other such file. However there were still some instances of the
strlen + strspn combination to check for that in WAL-related utilities
like pg_archivecleanup. Those checks can be replaced with the macros.
This patch makes use of the macros in those utilities and
which would make the code a bit easier to read.
Back-patch to 9.5.

If a file is removed from the source server, while pg_rewind is running, the
invocation of pg_read_binary_file() will fail. Use the just-added missing_ok
option to that function, to have it return NULL instead, and handle that
gracefully. And similarly for pg_ls_dir and pg_stat_file.

Spotted by Coverity and reported by Michael Paquier. Per discussion,
we don't necessarily care about making Coverity happy in all such
instances, but we can go ahead and change them where it otherwise
seems to improve the code.
This supplements the GNU libc bug #6530 workarounds introduced in commit
54cd4f0457. On affected systems, a
tar-format pg_basebackup failed when some filename beneath the data
directory was not valid character data in the postmaster/walsender
locale. Back-patch to 9.1, where pg_basebackup was introduced. Extant,
bug-prone conversion specifications receive only ASCII bytes or involve
low-importance messages.
RMGRDESCSOURCES is defined and used only in pg_xlogdump Makefile,
but pg_rewind Makefile mentioned it as extra files to remove in "make clean".
This patch removes that useless mention from pg_rewind Makefile.

string) of getopt_long().
* Use pg_free() or pfree() to free the memory allocated by pg_malloc() or

* Fix several typos.

The commit c22ed3d523 turned
the -i/--ignore-version options into no-ops and marked as deprecated.
Considering we shipped that in 8.4, it's time to remove all trace of
those switches, per discussion. We'd still have to wait a couple releases
before it'd be safe to use -i for something else, but it'd be a start.
