Backpatch to 9.3 where src/common was introduce, because a bugfix that
needs to be backpatched, requires the function. Earlier branches will
have to duplicate the code.
Windows versions later than Windows Server 2003 map "localhost" to ::1.
Account for that in the generated pg_hba.conf, fixing another oversight
in commit f6dc6dd5ba. Back-patch to 9.0,
like that commit.

Back-patch to 9.0 (all supported versions). This is mere
future-proofing in the context of the master branch, but commit
f6dc6dd5ba requires it of older branches.
Use SSPI authentication to allow connections exclusively from the OS
user that launched the test suite. This closes on Windows the
vulnerability that commit be76a6d39e
closed on other platforms. Users of "make installcheck" or custom test
harnesses can run "pg_regress --config-auth=DATADIR" to activate the
same authentication configuration that "make check" would use.
Back-patch to 9.0 (all supported versions).
Security: CVE-2014-0067
As 'ALTER TABLESPACE .. MOVE ALL' really didn't change the tablespace
but instead changed objects inside tablespaces, it made sense to
rework the syntax and supporting functions to operate under the
'ALTER (TABLE|INDEX|MATERIALIZED VIEW)' syntax and to be in
tablecmds.c.
Pointed out by Alvaro, who also suggested the new syntax.
Back-patch to 9.4.
Catch up with commit b8cc8f94730610c0189aa82dfec4ae6ce9b13e34's
introduction of the HAVE_UUID_OSSP symbol to the principal build
process. Back-patch to 9.4, where that commit appeared.
This function is pervasive on free software operating systems; import
NetBSD's implementation. Back-patch to 8.4, like the commit that will
harness it.
The recent addition of regression tests to uuid-ossp exposed the fact
that the MSVC build system wasn't being consistent about whether it was
building/testing that contrib module, ie, it would try to test the module
even when it hadn't built it. The same hazard was latent for sslinfo.
For the moment I just copied the more up-to-date logic from point A to
point B, but this is screaming for refactoring.
Per buildfarm results.
config.pl and buildenv.pl can be used to customize build settings when
using MSVC. They should never get committed into the common source tree.
Back-patch to 9.0; it looks like the rules were different in 8.4.

It's easy to forget using SYSTEMQUOTEs when constructing command strings
for system() or popen(). Even if we fix all the places missing it now, it is
bound to be forgotten again in the future. Introduce wrapper functions that
do the the extra quoting for you, and get rid of SYSTEMQUOTEs in all the
callers.
We previosly used SYSTEMQUOTEs in all the hard-coded command strings, and
this doesn't change the behavior of those. But user-supplied commands, like
archive_command, restore_command, COPY TO/FROM PROGRAM calls, as well as
pgbench's \shell, will now gain an extra pair of quotes. That is desirable,
but if you have existing scripts or config files that include an extra
pair of quotes, those might need to be adjusted.

Now that we're pretty much feature-frozen, it's time to update the checks
on system catalog foreign-key references.
(It looks like we missed doing this altogether for 9.3. Sigh.)
This has probably been broken for quite a long time. Buildfarm member
currawong's current results suggest that it's been broken since 9.1, so
backpatch this to that branch.
This only supports Python 2 - I will handle Python 3 separately, but
this is a fairly simple fix.
In order for this to work, walsenders need the optional ability to
connect to a database, so the "replication" keyword now allows true
or false, for backward-compatibility, and the new value "database"
(which causes the "dbname" parameter to be respected).
walsender needs to loop not only when idle but also when sending
decoded data to the user and when waiting for more xlog data to decode.
This means that there are now three separate loops inside walsender.c;
although some refactoring has been done here, this is still a bit ugly.

review by me.
This feature, building on previous commits, allows the write-ahead log
stream to be decoded into a series of logical changes; that is,
inserts, updates, and deletes and the transactions which contain them.
It is capable of handling decoding even across changes to the schema
of the effected tables. The output format is controlled by a
so-called "output plugin"; an example is included. To make use of
this in a real replication system, the output plugin will need to be
modified to produce output in the format appropriate to that system,
and to perform filtering.
Currently, information can be extracted from the logical decoding
system only via SQL; future commits will add the ability to stream
changes via walsender.

The ASLR in Windows 8/Windows 2012 can break PostgreSQL's shared memory. It
doesn't fail every time (which is explained by the Random part in ASLR), but
can fail with errors abut failing to reserve shared memory region.

This should make the MSVC build act more like builds for other platforms,
i.e. backend global variables will be automatically available to loadable
libraries without need for explicit PGDLLIMPORT marking.

Providing this information as plain text was doubtless worth the trouble
ten years ago, but it seems likely that hardly anyone reads it in this
format anymore. And the effort required to maintain these files (in the
form of extra-complex markup rules in the relevant parts of the SGML
documentation) is significant. So, let's stop doing that and rely solely
on the other documentation formats.
Per discussion, the plain-text INSTALL instructions might still be worth
their keep, so we continue to generate that file.
Rather than remove HISTORY and src/test/regress/README from distribution
tarballs entirely, replace them with simple stub files that tell the reader
where to find the relevant documentation. This is mainly to avoid possibly
breaking packaging recipes that expect these files to exist.
Back-patch to all supported branches, because simplifying the markup
requirements for release notes won't help much unless we do it in all
branches.
Replication slots are a crash-safe data structure which can be created
on either a master or a standby to prevent premature removal of
write-ahead log segments needed by a standby, as well as (with
hot_standby_feedback=on) pruning of tuples whose removal would cause
replication conflicts. Slots have some advantages over existing
techniques, as explained in the documentation.
In a few places, we refer to the type of replication slots introduced
by this patch as "physical" slots, because forthcoming patches for
logical decoding will also have slots, but with somewhat different
properties.

This makes it possible to store lwlocks as part of some other data
structure in the main shared memory segment, or in a dynamic shared
memory segment. There is still a main LWLock array and this patch does
not move anything out of it, but it provides necessary infrastructure
for doing that in the future.
This change is likely to increase the size of LWLockPadded on some
platforms, especially 32-bit platforms where it was previously only
16 bytes.
Patch by me. Review by Andres Freund and KaiGai Kohei.
In the MSVC build system we've never separated krb5 from gss,
and always built them both. Since the removal of native krb5
support, this parameter only controls GSSAPI, so rename it
accordingly.
krb5 has been deprecated since 8.3, and the recommended way to do
Kerberos authentication is using the GSSAPI authentication method
(which is still fully supported).
libpq retains the ability to identify krb5 authentication, but only
gives an error message about it being unsupported. Since all authentication
is initiated from the backend, there is no need to keep it at all
in the backend.
This adds a 'MOVE' sub-command to ALTER TABLESPACE which allows moving sets of
objects from one tablespace to another. This can be extremely handy and avoids
a lot of error-prone scripting. ALTER TABLESPACE ... MOVE will only move
objects the user owns, will notify the user if no objects were found, and can
be used to move ALL objects or specific types of objects (TABLES, INDEXES, or
MATERIALIZED VIEWS).
Previously, lookups of non-existent user names could return "Success";
it will now return "User does not exist" by resetting errno. This also
centralizes the user name lookup code in libpgport.
