The <acronym>GNU</acronym> <productname>Readline</productname> library is used by
2008-11-21 17:46:19 +01:00
default. It allows <application>psql</application> (the
PostgreSQL command line SQL interpreter) to remember each
command you type, and allows you to use arrow keys to recall and
edit previous commands. This is very helpful and is strongly
recommended. If you don't want to use it then you must specify
2009-06-17 23:58:49 +02:00
the <option>--without-readline</option> option to
2017-10-09 03:44:17 +02:00
<filename>configure</filename>. As an alternative, you can often use the
2005-12-04 04:52:29 +01:00
BSD-licensed <filename>libedit</filename> library, originally
developed on <productname>NetBSD</productname>. The
<filename>libedit</filename> library is

<option>--with-libedit-preferred</option> is used as an
2017-10-09 03:44:17 +02:00
option to <filename>configure</filename>. If you are using a package-based
2010-01-05 02:06:57 +01:00
Linux distribution, be aware that you need both the
2017-10-09 03:44:17 +02:00

To build the server programming language

in earlier versions, and in any case it is the choice of whomever

download section of our
2017-05-21 03:50:47 +02:00
website: <ulink url="https://www.postgresql.org/download/"></ulink>. You
2013-02-08 05:19:18 +01:00
should get a file named <filename>postgresql-&version;.tar.gz</filename>
or <filename>postgresql-&version;.tar.bz2</filename>. After
you have obtained the file, unpack it:
2004-12-24 19:37:26 +01:00

<userinput>gunzip postgresql-&version;.tar.gz</userinput>
<userinput>tar xf postgresql-&version;.tar</userinput>

(Use <command>bunzip2</command> instead of <command>gunzip</command> if
you have the <filename>.bz2</filename> file. Also, note that most
modern versions of <command>tar</command> can unpack compressed archives
directly, so you don't really need the
separate <command>gunzip</command> or <command>bunzip2</command> step.)
2004-12-24 19:37:26 +01:00

2017-10-09 03:44:17 +02:00
This is done by running the <filename>configure</filename> script. For a
2009-04-27 18:27:36 +02:00
default installation simply enter:
2004-12-24 19:37:26 +01:00
<screen>
<userinput>./configure</userinput>
</screen>
2009-04-27 18:27:36 +02:00
This script will run a number of tests to determine values for various
system dependent variables and detect any quirks of your
2004-12-24 19:37:26 +01:00
operating system, and finally will create several files in the
2019-08-30 21:44:00 +02:00
build tree to record what it found.
</para>
<para>
You can also run <filename>configure</filename> in a directory outside
the source tree, and then build there, if you want to keep the build
directory separate from the original source files. This procedure is
called a
2010-05-28 20:04:36 +02:00
<indexterm><primary>VPATH</primary></indexterm><firstterm>VPATH</firstterm>
build. Here's how:
<screen>
<userinput>mkdir build_dir</userinput>
<userinput>cd build_dir</userinput>
<userinput>/path/to/source/tree/configure [options go here]</userinput>
2014-02-12 23:29:19 +01:00
<userinput>make</userinput>
2010-05-28 20:04:36 +02:00
</screen>
2004-12-24 19:37:26 +01:00
</para>
<para>
The default configuration will build the server and utilities, as
well as all client applications and interfaces that require only a
C compiler. All files will be installed under
2017-10-09 03:44:17 +02:00
<filename>/usr/local/pgsql</filename> by default.
2004-12-24 19:37:26 +01:00
</para>
<para>
You can customize the build and installation process by supplying one
2019-08-30 21:44:00 +02:00
or more command line options to <filename>configure</filename>.
Typically you would customize the install location, or the set of
optional features that are built. <filename>configure</filename>
has a large number of options, which are described in
<xref linkend="configure-options"/>.
</para>
<para>
Also, <filename>configure</filename> responds to certain environment
variables, as described in <xref linkend="configure-envvars"/>.
These provide additional ways to customize the configuration.
</para>
</step>
<step id="build">
<title>Build</title>
<para>
To start the build, type either of:
<screen>
<userinput>make</userinput>
<userinput>make all</userinput>
</screen>
(Remember to use <acronym>GNU</acronym> <application>make</application>.)
The build will take a few minutes depending on your
hardware. The last line displayed should be:
<screen>
All of PostgreSQL successfully made. Ready to install.
</screen>
</para>
<para>
If you want to build everything that can be built, including the
documentation (HTML and man pages), and the additional modules
(<filename>contrib</filename>), type instead:
<screen>
<userinput>make world</userinput>
</screen>
The last line displayed should be:
<screen>
PostgreSQL, contrib, and documentation successfully made. Ready to install.
</screen>
</para>
<para>
If you want to invoke the build from another makefile rather than
manually, you must unset <varname>MAKELEVEL</varname> or set it to zero,
for instance like this:
<programlisting>
build-postgresql:
$(MAKE) -C postgresql MAKELEVEL=0 all
</programlisting>
Failure to do that can lead to strange error messages, typically about
missing header files.
</para>
</step>
<step>
<title>Regression Tests</title>
<indexterm>
<primary>regression test</primary>
</indexterm>
<para>
If you want to test the newly built server before you install it,
you can run the regression tests at this point. The regression
tests are a test suite to verify that <productname>PostgreSQL</productname>
runs on your machine in the way the developers expected it
to. Type:
<screen>
<userinput>make check</userinput>
</screen>
(This won't work as root; do it as an unprivileged user.)
See <xref linkend="regress"/> for
detailed information about interpreting the test results. You can
repeat this test at any later time by issuing the same command.
</para>
</step>
<step id="install">
<title>Installing the Files</title>
<note>
<para>
If you are upgrading an existing system be sure to read
<xref linkend="upgrading"/>,
which has instructions about upgrading a
cluster.
</para>
</note>
<para>
To install <productname>PostgreSQL</productname> enter:
<screen>
<userinput>make install</userinput>
</screen>
This will install files into the directories that were specified
in <xref linkend="configure"/>. Make sure that you have appropriate
permissions to write into that area. Normally you need to do this
step as root. Alternatively, you can create the target
directories in advance and arrange for appropriate permissions to
be granted.
</para>
<para>
To install the documentation (HTML and man pages), enter:
<screen>
<userinput>make install-docs</userinput>
</screen>
</para>
<para>
If you built the world above, type instead:
<screen>
<userinput>make install-world</userinput>
</screen>
This also installs the documentation.
</para>
<para>
You can use <literal>make install-strip</literal> instead of
<literal>make install</literal> to strip the executable files and
libraries as they are installed. This will save some space. If
you built with debugging support, stripping will effectively
remove the debugging support, so it should only be done if
debugging is no longer needed. <literal>install-strip</literal>
tries to do a reasonable job saving space, but it does not have
perfect knowledge of how to strip every unneeded byte from an
executable file, so if you want to save all the disk space you
possibly can, you will have to do manual work.
</para>
<para>
The standard installation provides all the header files needed for client
application development as well as for server-side program
development, such as custom functions or data types written in C.
(Prior to <productname>PostgreSQL</productname> 8.0, a separate <literal>make
install-all-headers</literal> command was needed for the latter, but this
step has been folded into the standard install.)
</para>
<formalpara>
<title>Client-only installation:</title>
<para>
If you want to install only the client applications and
interface libraries, then you can use these commands:
<screen>
<userinput>make -C src/bin install</userinput>
<userinput>make -C src/include install</userinput>
<userinput>make -C src/interfaces install</userinput>
<userinput>make -C doc install</userinput>
</screen>
<filename>src/bin</filename> has a few binaries for server-only use,
but they are small.
</para>
</formalpara>
</step>
</procedure>
<formalpara>
<title>Uninstallation:</title>
<para>
To undo the installation use the command <command>make
uninstall</command>. However, this will not remove any created directories.
</para>
</formalpara>
<formalpara>
<title>Cleaning:</title>
<para>
After the installation you can free disk space by removing the built
files from the source tree with the command <command>make
clean</command>. This will preserve the files made by the <command>configure</command>
program, so that you can rebuild everything with <command>make</command>
later on. To reset the source tree to the state in which it was
distributed, use <command>make distclean</command>. If you are going to
build for several platforms within the same source tree you must do
this and re-configure for each platform. (Alternatively, use
a separate build tree for each platform, so that the source tree
remains unmodified.)
</para>
</formalpara>
<para>
If you perform a build and then discover that your <command>configure</command>
options were wrong, or if you change anything that <command>configure</command>
investigates (for example, software upgrades), then it's a good
idea to do <command>make distclean</command> before reconfiguring and
rebuilding. Without this, your changes in configuration choices
might not propagate everywhere they need to.

<command>configure</command>'s command line options are explained below.
This list is not exhaustive (use <literal>./configure --help</literal>
to get one that is). The options not covered here are meant for
advanced use-cases such as cross-compilation, and are documented in
the standard Autoconf documentation.
</para>
<sect3 id="configure-options-locations">
<title>Installation Locations</title>
<para>
These options control where <literal>make install</literal> will put
the files. The <option>--prefix</option> option is sufficient for
most cases. If you have special needs, you can customize the
installation subdirectories with the other options described in this
section. Beware however that changing the relative locations of the
different subdirectories may render the installation non-relocatable,
meaning you won't be able to move it after installation.
(The <literal>man</literal> and <literal>doc</literal> locations are
not affected by this restriction.) For relocatable installs, you
might want to use the <literal>--disable-rpath</literal> option
described later.

Refer to OS X as "macOS", except for the port name which is still "darwin".
We weren't terribly consistent about whether to call Apple's OS "OS X"
or "Mac OS X", and the former is probably confusing to people who aren't
Apple users. Now that Apple has rebranded it "macOS", follow their lead
to establish a consistent naming pattern. Also, avoid the use of the
ancient project name "Darwin", except as the port code name which does not
seem desirable to change. (In short, this patch touches documentation and
comments, but no actual code.)
I didn't touch contrib/start-scripts/osx/, either. I suspect those are
obsolete and due for a rewrite, anyway.
I dithered about whether to apply this edit to old release notes, but
those were responsible for quite a lot of the inconsistencies, so I ended
up changing them too. Anyway, Apple's being ahistorical about this,
so why shouldn't we be?

Support timezone abbreviations that sometimes change.
Up to now, PG has assumed that any given timezone abbreviation (such as
"EDT") represents a constant GMT offset in the usage of any particular
region; we had a way to configure what that offset was, but not for it
to be changeable over time. But, as with most things horological, this
view of the world is too simplistic: there are numerous regions that have
at one time or another switched to a different GMT offset but kept using
the same timezone abbreviation. Almost the entire Russian Federation did
that a few years ago, and later this month they're going to do it again.
And there are similar examples all over the world.
To cope with this, invent the notion of a "dynamic timezone abbreviation",
which is one that is referenced to a particular underlying timezone
(as defined in the IANA timezone database) and means whatever it currently
means in that zone. For zones that use or have used daylight-savings time,
the standard and DST abbreviations continue to have the property that you
can specify standard or DST time and get that time offset whether or not
DST was theoretically in effect at the time. However, the abbreviations
mean what they meant at the time in question (or most recently before that
time) rather than being absolutely fixed.
The standard abbreviation-list files have been changed to use this behavior
for abbreviations that have actually varied in meaning since 1970. The
old simple-numeric definitions are kept for abbreviations that have not
changed, since they are a bit faster to resolve.
While this is clearly a new feature, it seems necessary to back-patch it
into all active branches, because otherwise use of Russian zone
abbreviations is going to become even more problematic than it already was.
This change supersedes the changes in commit 513d06ded et al to modify the
fixed meanings of the Russian abbreviations; since we've not shipped that
yet, this will avoid an undesirably incompatible (not to mention incorrect)
change in behavior for timestamps between 2011 and 2014.
This patch makes some cosmetic changes in ecpglib to keep its usage of
datetime lookup tables as similar as possible to the backend code, but
doesn't do anything about the increasingly obsolete set of timezone
abbreviation definitions that are hard-wired into ecpglib. Whatever we
do about that will likely not be appropriate material for back-patching.
Also, a potential free() of a garbage pointer after an out-of-memory
failure in ecpglib has been fixed.
This patch also fixes pre-existing bugs in DetermineTimeZoneOffset() that
caused it to produce unexpected results near a timezone transition, if
both the "before" and "after" states are marked as standard time. We'd
only ever thought about or tested transitions between standard and DST
time, but that's not what's happening when a zone simply redefines their
base GMT offset.
In passing, update the SGML documentation to refer to the Olson/zoneinfo/
zic timezone database as the "IANA" database, since it's now being
maintained under the auspices of IANA.
2014-10-16 21:22:10 +02:00
database is in fact compatible with the IANA time zone
2007-08-25 22:29:25 +02:00
database provided by many operating systems such as FreeBSD,
Linux, and Solaris, so it would be redundant to install it again.
When this option is used, the system-supplied time zone database
in <replaceable>DIRECTORY</replaceable> is used instead of the one
included in the PostgreSQL source distribution.
<replaceable>DIRECTORY</replaceable> must be specified as an
absolute path. <filename>/usr/share/zoneinfo</filename> is a
2007-08-20 10:53:12 +02:00
likely directory on some operating systems. Note that the
2007-08-25 22:29:25 +02:00
installation routine will not detect mismatching or erroneous time
zone data. If you use this option, you are advised to run the
regression tests to verify that the time zone data you have
2017-10-09 03:44:17 +02:00
pointed to works correctly with <productname>PostgreSQL</productname>.

This option is mainly aimed at binary package distributors
who know their target operating system well. The main
advantage of using this option is that the PostgreSQL package
won't need to be upgraded whenever any of the many local
2007-08-25 22:29:25 +02:00
daylight-saving time rules change. Another advantage is that
2011-04-08 17:36:05 +02:00
PostgreSQL can be cross-compiled more straightforwardly if the
2007-08-25 22:29:25 +02:00

Do not mark <productname>PostgreSQL</productname>'s executables
to indicate that they should search for shared libraries in the
installation's library directory (see <option>--libdir</option>).
On most platforms, this marking uses an absolute path to the
library directory, so that it will be unhelpful if you relocate
the installation later. However, you will then need to provide
some other way for the executables to find the shared libraries.
Typically this requires configuring the operating system's
dynamic linker to search the library directory; see
<xref linkend="install-post-shlibs"/> for more detail.

Set the <firstterm>segment size</firstterm>, in gigabytes. Large tables are
divided into multiple operating-system files, each of size equal
to the segment size. This avoids problems with file size limits
that exist on many platforms. The default segment size, 1 gigabyte,
is safe on all supported platforms. If your operating system has
<quote>largefile</quote> support (which most do, nowadays), you can use
a larger segment size. This can be helpful to reduce the number of
file descriptors consumed when working with very large tables.
But be careful not to select a value larger than is supported
by your platform and the file systems you intend to use. Other
tools you might wish to use, such as <application>tar</application>, could
also set limits on the usable file size.
It is recommended, though not absolutely required, that this value
be a power of 2.
Note that changing this value breaks on-disk database compatibility,
meaning you cannot use <command>pg_upgrade</command> to upgrade to
a build with a different segment size.

You can specify environment variables on the

<screen>
<userinput>./configure CC=/opt/bin/gcc CFLAGS='-O2 -pipe'</userinput>

In this usage an environment variable is little different from a

You can also set such variables beforehand:

<userinput>export CC=/opt/bin/gcc</userinput>
<userinput>export CFLAGS='-O2 -pipe'</userinput>
<userinput>./configure</userinput>

Sometimes it is useful to add compiler flags after-the-fact to the set
2017-10-09 03:44:17 +02:00
that were chosen by <filename>configure</filename>. An important example is
that <application>gcc</application>'s <option>-Werror</option> option cannot be included
in the <envar>CFLAGS</envar> passed to <filename>configure</filename>, because
it will break many of <filename>configure</filename>'s built-in tests. To add
2017-02-17 22:11:02 +01:00
such flags, include them in the <envar>COPT</envar> environment variable
2017-10-09 03:44:17 +02:00
while running <filename>make</filename>. The contents of <envar>COPT</envar>
2017-02-17 22:11:02 +01:00
are added to both the <envar>CFLAGS</envar> and <envar>LDFLAGS</envar>
2017-10-09 03:44:17 +02:00
options set up by <filename>configure</filename>. For example, you could do
2017-02-17 22:11:02 +01:00
<screen>
2017-10-09 03:44:17 +02:00

or

If using GCC, it is best to build with an optimization level of
2017-10-09 03:44:17 +02:00
at least <option>-O1</option>, because using no optimization
(<option>-O0</option>) disables some important compiler warnings (such
2011-12-02 23:08:33 +01:00
as the use of uninitialized variables). However, non-zero
optimization levels can complicate debugging because stepping
through compiled code will usually not match up one-to-one with
source code lines. If you get confused while trying to debug
optimized code, recompile the specific files of interest with
2017-10-09 03:44:17 +02:00
<option>-O0</option>. An easy way to do this is by passing an option
to <application>make</application>: <command>make PROFILE=-O0 file.o</command>.

The method to set the shared library search path varies between
2009-04-27 18:27:36 +02:00
platforms, but the most widely-used method is to set the
2017-10-09 03:44:17 +02:00
environment variable <envar>LD_LIBRARY_PATH</envar> like so: In Bourne
shells (<command>sh</command>, <command>ksh</command>, <command>bash</command>, <command>zsh</command>):
2004-12-24 19:37:26 +01:00
<programlisting>
LD_LIBRARY_PATH=/usr/local/pgsql/lib
export LD_LIBRARY_PATH
</programlisting>
2017-10-09 03:44:17 +02:00
or in <command>csh</command> or <command>tcsh</command>:
2004-12-24 19:37:26 +01:00
<programlisting>
setenv LD_LIBRARY_PATH /usr/local/pgsql/lib
</programlisting>
2017-10-09 03:44:17 +02:00
Replace <literal>/usr/local/pgsql/lib</literal> with whatever you set
2017-11-23 15:39:47 +01:00
<option><literal>--libdir</literal></option> to in <xref linkend="configure"/>.
2004-12-24 19:37:26 +01:00
You should put these commands into a shell start-up file such as

AIX can be somewhat peculiar with regards to the way it does
memory management. You can have a server with many multiples of
gigabytes of RAM free, but still get out of memory or address
space errors when running applications. One example

Another example is out of memory errors in the PostgreSQL server
2016-08-05 20:35:09 +02:00
logs, with every memory allocation near or greater than 256 MB
2008-11-24 12:59:37 +01:00
failing.
</para>
<para>
The overall cause of all these problems is the default bittedness
and memory model used by the server process. By default, all
binaries built on AIX are 32-bit. This does not depend upon
hardware type or kernel in use. These 32-bit processes are
2016-08-05 20:35:09 +02:00
limited to 4 GB of memory laid out in 256 MB segments using one
of a few models. The default allows for less than 256 MB in the
2008-11-24 12:59:37 +01:00
heap as it shares a single segment with the stack.
</para>
<para>
2017-03-23 19:16:45 +01:00
In the case of the <literal>plperl</literal> example, above,
2008-11-24 12:59:37 +01:00
check your umask and the permissions of the binaries in your
PostgreSQL installation. The binaries involved in that example
were 32-bit and installed as mode 750 instead of 755. Due to the
permissions being set in this fashion, only the owner or a member
of the possessing group can load the library. Since it isn't
world-readable, the loader places the object into the process'
heap instead of the shared library segments where it would
otherwise be placed.
</para>
<para>
The <quote>ideal</quote> solution for this is to use a 64-bit
build of PostgreSQL, but that is not always practical, because
systems with 32-bit processors can build, but not run, 64-bit
binaries.
</para>
<para>
If a 32-bit binary is desired, set <symbol>LDR_CNTRL</symbol> to
<literal>MAXDATA=0x<replaceable>n</replaceable>0000000</literal>,
where 1 <= n <= 8, before starting the PostgreSQL server,
and try different values and <filename>postgresql.conf</filename>
settings to find a configuration that works satisfactorily. This
use of <symbol>LDR_CNTRL</symbol> tells AIX that you want the
server to have <symbol>MAXDATA</symbol> bytes set aside for the
2016-08-05 20:35:09 +02:00
heap, allocated in 256 MB segments. When you find a workable
2008-11-24 12:59:37 +01:00
configuration,
<command>ldedit</command> can be used to modify the binaries so
that they default to using the desired heap size. PostgreSQL can
also be rebuilt, passing <literal>configure
LDFLAGS="-Wl,-bmaxdata:0x<replaceable>n</replaceable>0000000"</literal>
to achieve the same effect.
</para>
<para>
For a 64-bit build, set <envar>OBJECT_MODE</envar> to 64 and
pass <literal>CC="gcc -maix64"</literal>
and <literal>LDFLAGS="-Wl,-bbigtoc"</literal>
to <command>configure</command>. (Options for
<command>xlc</command> might differ.) If you omit the export of
<envar>OBJECT_MODE</envar>, your build may fail with linker errors. When
<envar>OBJECT_MODE</envar> is set, it tells AIX's build utilities
2017-10-09 03:44:17 +02:00
such as <command>ar</command>, <command>as</command>, and <command>ld</command> what
2008-11-24 12:59:37 +01:00
type of objects to default to handling.
</para>
<para>
By default, overcommit of paging space can happen. While we have
not seen this occur, AIX will kill processes when it runs out of
memory and the overcommit is accessed. The closest to this that
we have seen is fork failing because the system decided that
there was not enough memory for another process. Like many other
parts of AIX, the paging space allocation method and
out-of-memory kill is configurable on a system- or process-wide
basis if this becomes a problem.

On recent <productname>macOS</productname> releases, it's necessary to
embed the <quote>sysroot</quote> path in the include switches used to
find some system header files. This results in the outputs of
the <application>configure</application> script varying depending on
which SDK version was used during <application>configure</application>.
That shouldn't pose any problem in simple scenarios, but if you are
trying to do something like building an extension on a different machine
than the server code was built on, you may need to force use of a
different sysroot path. To do that, set <varname>PG_SYSROOT</varname>,
for example
<programlisting>
make PG_SYSROOT=<replaceable>/desired/path</replaceable> all
</programlisting>
To find out the appropriate path on your machine, run
<programlisting>
xcodebuild -version -sdk macosx Path
</programlisting>
Note that building an extension using a different sysroot version than
was used to build the core server is not really recommended; in the
worst case it could result in hard-to-debug ABI inconsistencies.
</para>
<para>
You can also select a non-default sysroot path when configuring, by

Most Postgres developers just turn off SIP, though.
