These variables no longer have any useful purpose, since there's no reason
to special-case brute force timezones now that we have a valid
session_timezone setting for them. Remove the variables, and remove the
SET/SHOW TIME ZONE code that deals with them.
The user-visible impact of this is that SHOW TIME ZONE will now show a
POSIX-style zone specification, in the form "<+-offset>-+offset", rather
than an interval value when a brute-force zone has been set. While perhaps
less intuitive, this is a better definition than before because it's
actually possible to give that string back to SET TIME ZONE and get the
same behavior, unlike what used to happen.
We did not previously mention the angle-bracket syntax when describing
POSIX timezone specifications; add some documentation so that people
can figure out what these strings do. (There's still quite a lot of
undocumented functionality there, but anybody who really cares can
go read the POSIX spec to find out about it. In practice most people
seem to prefer Olsen-style city names anyway.)
SGML documentation, as well as code comments, failed to note that an FDW's
validator will be applied to foreign-table options for foreign tables using
the FDW.

We don't need two index entries for lo_create pointing at the same section.
It's a bit pedantic for the toolchain to warn about this, but warn it does.
With these, one need no longer manipulate large object descriptors and
extract numeric constants from header files in order to read and write
large object contents from SQL.

Move random() and setseed() to a separate table, to have them grouped

Add a makefile rule for building PDFs with FOP. Two new build targets
in doc/src/sgml are postgres-A4-fop.pdf and postgres-US-fop.pdf.
Run .fo output through xmllint for reformatting, so that errors are
easier to find. (The default output has hardly any line breaks, so you
might be looking for an error in column 20000.)
Set some XSLT parameters to optimize for building with FOP.
Remove some redundant or somewhat useless chapterinfo/author

Previously, unless all columns were auto-updateable, we wouldn't
inserts, updates, or deletes, or at least not without a rule or trigger;
now, we'll allow inserts and updates that target only the auto-updateable
columns, and deletes even if there are no auto-updateable columns at
all provided the view definition is otherwise suitable.

Although previously-introduced APIs allow the process that registers a
background worker to obtain the worker's PID, there's no way to prevent
a worker that is not currently running from being restarted. This
patch introduces a new API TerminateBackgroundWorker() that prevents
the background worker from being restarted, terminates it if it is
currently running, and causes it to be unregistered if or when it is
not running.
Patch by me. Review by Michael Paquier and KaiGai Kohei.
Development of IRIX has been discontinued, and support is scheduled
to end in December of 2013. Therefore, there will be no supported
versions of this operating system by the time PostgreSQL 9.4 is
released. Furthermore, we have no maintainer for this platform.
The default table of contents in the XSLT HTML build is much too big and
deep. Configure it to look more like the one that is currently being
produced by the DSSSL build.
All of these platforms are very much obsolete.
As far as I can determine, the last version of SINIX, later renamed
Reliant, occurred some time between 2002 and 2005.
The last release of SunOS that would run on a sun3 was released in
November of 1991; the last release of OpenBSD which supported that
platform was in 2001. The highest clock speed of any processor in
the family was 25MHz.
The NS32K (national semiconductor 320xx) architecture was retired
in 1990.
Support can be re-added if a maintainer emerges for any of these
platforms, but it seems unlikely.

The XSLT toolchain requires an empty <index> element where the index is
supposed to appear. Add that with conditionals to hide it from the
DSSSL build.
The previous plan of having the check-tabs target a prerequisite of
"all" and "distprep" caused make distcheck to fail because make -q
distprep would never be satisfied. Put check-tabs into the html target
instead, so it is only called when a build actually happens.
make maintainer-check was obscure and rarely called in practice, and
many breakages were missed. Fold everything that make maintainer-check
used to do into the normal build. Specifically:
- Call duplicate_oids when genbki.pl is called.
- Check for tabs in SGML files when the documentation is built.
- Run msgfmt with the -c option during the regular build. Add an
additional configure check to see whether we are using the GNU
version. (make maintainer-check probably used to fail with non-GNU
msgfmt.)
Keep maintainer-check as around as phony target for the time being in
case anyone is calling it. But it won't do anything anymore.
Change the input/output format to {A,B,C}, to match the internal
representation.
Complete the implementations of line_in, line_out, line_recv, line_send.
Remove comments and error messages about the line type not being
implemented. Add regression tests for existing line operators and
functions.

REFRESH MATERIALIZED VIEW CONCURRENTLY was broken for any matview
containing a column of a type without a default btree operator
class. It also did not produce results consistent with a non-
concurrent REFRESH or a normal view if any column was of a type
which allowed user-visible differences between values which
compared as equal according to the type's default btree opclass.
Concurrent matview refresh was modified to use the new operators
to solve these problems.
Documentation was added for record comparison, both for the
default btree operator class for record, and the newly added
operators. Regression tests now check for proper behavior both
for a matview with a box column and a matview containing a citext
column.

Previously, arbitray system columns could be mentioned in table
constraints, but they were not correctly checked at runtime, because
the values weren't actually set correctly in the tuple. Since it
seems easy enough to initialize the table OID properly, do that,
and continue allowing that column, but disallow the rest unless and
until someone figures out a way to make them work properly.
No back-patch, because this doesn't seem important enough to take the
risk of destabilizing the back branches. In fact, this will pose a
dump-and-reload hazard for those upgrading from previous versions:
constraints that were accepted before but were not correctly enforced
will now either be enforced correctly or not accepted at all. Either
could result in restore failures, but in practice I think very few
users will notice the difference, since the use case is pretty
marginal anyway and few users will be relying on features that have
not historically worked.

Commit 95ef6a3448 removed the
ability to create rules on an individual column as of 7.3, but
left some residual code which has since been useless. This cleans
up that dead code without any change in behavior other than
dropping the useless column from the catalog.
