<productname>PostgreSQL</productname> database cluster. A database

cluster is a collection of databases that are managed by a single

server instance.

Creating a database cluster consists of creating the directories in
|
|
|
|
which the database data will live, generating the shared catalog
|
|
|
|
tables (tables that belong to the whole cluster rather than to any
|
|
|
|
particular database), and creating the <literal>template1</literal>
|
2010-11-23 21:27:50 +01:00
|
|
|
and <literal>postgres</literal> databases. When you later create a
|
|
|
|
new database, everything in the <literal>template1</literal> database is
|
2005-06-21 06:02:34 +02:00
|
|
|
copied. (Therefore, anything installed in <literal>template1</literal>
|
|
|
|
is automatically copied into each database created later.)
|
|
|
|
The <literal>postgres</literal> database is a default database meant
|
|
|
|
for use by users, utilities and third party applications.

Although <command>initdb</command> will attempt to create the
|
|
|
|
specified data directory, it might not have permission if the parent
|
|
|
|
directory of the desired data directory is root-owned. To initialize
|
|
|
|
in such a setup, create an empty data directory as root, then use
|
|
|
|
<command>chown</command> to assign ownership of that directory to the
|
|
|
|
database user account, then <command>su</command> to become the
|
|
|
|
database user to run <command>initdb</command>.

<command>initdb</command> must be run as the user that will own the

|
|
server process, because the server needs to have access to the
|
|
|
|
files and directories that <command>initdb</command> creates.
|
Update reference documentation on may/can/might:
Standard English uses "may", "can", and "might" in different ways:
may - permission, "You may borrow my rake."
can - ability, "I can lift that log."
might - possibility, "It might rain today."
Unfortunately, in conversational English, their use is often mixed, as
in, "You may use this variable to do X", when in fact, "can" is a better
choice. Similarly, "It may crash" is better stated, "It might crash".
2007-02-01 00:26:05 +01:00
|
|
|
Since the server cannot be run as root, you must not run
|
2001-09-08 17:24:00 +02:00
|
|
|
<command>initdb</command> as root either. (It will in fact refuse
|
|
|
|
to do so.)

For security reasons the new cluster created by <command>initdb</command>
|
|
|
|
will only be accessible by the cluster owner by default. The
|
|
|
|
<option>--allow-group-access</option> option allows any user in the same
|
|
|
|
group as the cluster owner to read files in the cluster. This is useful
|
|
|
|
for performing backups as a non-privileged user.

<command>initdb</command> initializes the database cluster's default
|
2008-09-23 11:20:39 +02:00
|
|
|
locale and character set encoding. The character set encoding,
|
2017-10-09 03:44:17 +02:00
|
|
|
collation order (<literal>LC_COLLATE</literal>) and character set classes
|
|
|
|
(<literal>LC_CTYPE</literal>, e.g. upper, lower, digit) can be set separately
|
2008-09-23 11:20:39 +02:00
|
|
|
for a database when it is created. <command>initdb</command> determines
|
|
|
|
those settings for the <literal>template1</literal> database, which will
|
|
|
|
serve as the default for all other databases.
|
|
|
|
</para>
|
|
|

<para>

To alter the default collation order or character set classes, use the
|
|
|
|
<option>--lc-collate</option> and <option>--lc-ctype</option> options.
|
2017-10-09 03:44:17 +02:00
|
|
|
Collation orders other than <literal>C</literal> or <literal>POSIX</literal> also have
|
2008-09-23 11:20:39 +02:00
|
|
|
a performance penalty. For these reasons it is important to choose the
|
2010-11-23 21:27:50 +01:00
|
|
|
right locale when running <command>initdb</command>.

The remaining locale categories can be changed later when the server
|
|
|
|
is started. You can also use <option>--locale</option> to set the
|
|
|
|
default for all locale categories, including collation order and
|
2017-10-09 03:44:17 +02:00
|
|
|
character set classes. All server locale values (<literal>lc_*</literal>) can
|
|
|
|
be displayed via <command>SHOW ALL</command>.

Make WAL segment size configurable at initdb time.
For performance reasons a larger segment size than the default 16MB
can be useful. A larger segment size has two main benefits: Firstly,
in setups using archiving, it makes it easier to write scripts that
can keep up with higher amounts of WAL, secondly, the WAL has to be
written and synced to disk less frequently.
But at the same time large segment size are disadvantageous for
smaller databases. So far the segment size had to be configured at
compile time, often making it unrealistic to choose one fitting to a
particularly load. Therefore change it to a initdb time setting.
This includes a breaking changes to the xlogreader.h API, which now
requires the current segment size to be configured. For that and
similar reasons a number of binaries had to be taught how to recognize
the current segment size.

Set the <firstterm>WAL segment size</firstterm>, in megabytes. This
|
|
|
|
is the size of each individual file in the WAL log. The default size
|
|
|
|
is 16 megabytes. The value must be a power of 2 between 1 and 1024
|
|
|
|
(megabytes). This option can only be set during initialization, and

It may be useful to adjust this size to control the granularity of
|
|
|
|
WAL log shipping or archiving. Also, in databases with a high volume
|
|
|
|
of WAL, the sheer number of WAL files per directory can become a
|
|
|
|
performance and management problem. Increasing the WAL file size
|
|
|
|
will reduce the number of WAL files.

Update reference documentation on may/can/might:
Standard English uses "may", "can", and "might" in different ways:
may - permission, "You may borrow my rake."
can - ability, "I can lift that log."
might - possibility, "It might rain today."
Unfortunately, in conversational English, their use is often mixed, as
in, "You may use this variable to do X", when in fact, "can" is a better
choice. Similarly, "It may crash" is better stated, "It might crash".
