Description

</title>
|
|
<para>
|
|
<application>initdb</application> creates a new
|
|
<productname>Postgres</productname> database system.
|
|
A database system is a
|
|
collection of databases that are all administered by the same Unix user
|
|
and managed by a single postmaster.
|
|
</para>
|
|
<para>
|
|
Creating a database system consists of creating the directories in which
|
|
the database data will live, generating the shared catalog tables
|
|
(tables that don't belong to any particular database), and
|
|
creating the <literal>template1</literal>
|
|
database. What is the <literal>template1</literal>
|
|
database? When you create a database, <productname>Postgres</productname>
|
|
does it by copying
|
|
everything from the <literal>template1</literal>
|
|
database. It contains catalog tables filled in for things like the
|
|
builtin types.
|
|
</para>
|
|
<para>
|
|
After <application>initdb</application>
|
|
creates the database, it completes the initialization by running
|
|
<application>vacuum</application>, which resets some optimization parameters.
|
|
</para>
|
|
<para>
|
|
There are three ways to give parameters to <application>initdb</application>.
|
|
|
|
<itemizedlist>
|
|
<listitem>
|
|
<para>
|
|
You can use <application>initdb</application> command options.
|
|
</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>
|
|
You can set environment
|
|
variables before invoking <application>initdb</application>.
|
|
</para>
|
|
</listitem>
|
|
|
|
<listitem>
|
|
<para>
|
|
You can have a program called <application>postconfig</application>
|
|
in your Unix command search path.
|
|
<application>initdb</application> invokes that program and that program then writes
|
|
<application>initdb</application> parameters to its standard output stream.
|
|
This third option is not a common thing to do, however.
|
|
</para>
|
|
</listitem>
|
|
</itemizedlist>
|
|
</para>
|
|
|
|
<para>
|
|
Command options always override parameters specified any other way.
|
|
The values returned by <application>postconfig</application>
|
|
override any environment variables, but your
|
|
<application>postconfig</application>
|
|
program may base its output on the environment variables if you want
|
|
their values to be used.
|
|
</para>
|
|
|
|
<para>
|
|
The value that <application>postconfig</application>
|
|
outputs must have the format
|
|
<synopsis>
|
|
<replaceable>var1</replaceable>=<replaceable class="parameter">value1</replaceable> <replaceable class="parameter">var2</replaceable>=<replaceable class="parameter">value2</replaceable> ...
|
|
</synopsis>
|
|
|
|
It can output nothing if it doesn't want to supply any parameters.
|
|
The <replaceable>var</replaceable> values are equal to
|
|
the corresponding environment variable
|
|
names. For example,
|
|
<programlisting>
|
|
PGDATA=/tmp/postgres_test
|
|
</programlisting>
|
|
has the
|
|
same effect as invoking <application>initdb</application>
|
|
with an environment variable called <envar>PGDATA</envar> whose value is
|
|
<filename>/tmp/postgres_test</filename>.
