Starting postmaster
</title>
<para>
To start up <application>postmaster</application>:
<programlisting>
> pg_ctl start
</programlisting>
</para>
<para>
If -w is supplied, pg_ctl waits for the database server comes up, by
watching for creation of the pid file (PGDATA/postmaster.pid), for up
to 60 seconds.
</para>
<para>
Parameters to invoke <application>postmaster</application> are
taken from the following sources:
<itemizedlist>
<listitem>
<para>
Path to postmaster: found in the command search path.
</para>
</listitem>
<listitem>
<para>
Database directory: <envar>PGDATA</envar> environment variable.
</para>
</listitem>
<listitem>
<para>
Other parameters:
<filename><envar>PGDATA</envar>/postmaster.opts.default</filename>.
</para>
</listitem>
</itemizedlist>
</para>
<para>
<filename>postmaster.opts.default</filename> contains parameters
for <application>postmaster</application>. With a
default installation, the <option>-S</option> option is enabled.
So <command>pg_ctl start</command> implies:
<programlisting>
postmaster -S
</programlisting>
</para>
<para>
Note that <filename>postmaster.opts.default</filename> is
installed by <application>initdb</application> from
<filename>lib/postmaster.opts.default.sample</filename>
under the <productname>Postgres</productname> installation
directory (<filename>lib/postmaster.opts.default.sample</filename>
is copied from
<filename>src/bin/pg_ctl/postmaster.opts.default.sample</filename>
while installing <productname>Postgres</productname>).
</para>
<para>
To override the default parameters you can use <option>-D</option>,
<option>-p</option> and <option>-o</option> options.
</para>
<para>
An example of starting the
<application>postmaster</application>, blocking until
postmaster comes up is:
<programlisting>
> pg_ctl -w start
</programlisting>
</para>
<para>
To specify the <application>postmaster</application> binary path,
try:
<programlisting>
> pg_ctl -p /usr/local/pgsq/bin/postmaster start
</programlisting>
</para>
<para>
For a <application>postmaster</application> using port 5433, and
running without <function>fsync</function>, use:
<programlisting>
> pg_ctl -o "-o -F -p 5433" start
</programlisting>
</para>
</refsect2>
<refsect2 id="R2-APP-PGCTL-4">
<title>
Stopping postmaster
</title>
<para>
<programlisting>
> pg_ctl stop
</programlisting>
stops postmaster. Using the <option>-m</option> switch allows one
to control <emphasis>how</emphasis> the backend shuts down.
<option>-w</option>
waits for postmaster to shut down.
<option>-m</option> specifies the shut down mode.
</para>
</refsect2>
<refsect2 id="R2-APP-PGCTL-5">
<title>
Restarting postmaster
</title>
<para>
This is almost equivalent to stopping the
<application>postmaster</application> then starting it
again except that the parameters used before stopping
it would be used too. This is done by saving them in
$<envar>PGDATA</envar>/postmaster.opts file.
<option>-w</option>, <option>-D</option>, <option>-m</option>,
<option>-fast</option>, <option>-immediate</option> and
<option>-o</option>
can also be used in the restarting mode and they have same meanings as
described above.
</para>
<para>
To restart <application>postmaster</application> in the simplest
form:
<programlisting>
> pg_ctl restart
</programlisting>
</para>
<para>
To restart <application>postmaster</application>,
waiting for it to shut down and to come up:
<programlisting>
> pg_ctl -w restart
</programlisting>
</para>
<para>
To restart using port 5433 and disabling fsync after restarting:
<programlisting>
> pg_ctl -o "-o -F -p 5433" restart
</programlisting>
</para>
</refsect2>
<refsect2 id="R2-APP-PGCTL-6">
<title>
postmaster status
</title>
<para>
To get status information from postmaster:
<programlisting>
> pg_ctl status
</programlisting>
</para>
<para>
Here is a sample output from <application>pg_ctl</application>:
<programlisting>
pg_ctl: postmaster is running (pid: 13718)
options are:
/usr/local/src/pgsql/current/bin/postmaster
-p 5433
-D /usr/local/src/pgsql/current/data
-B 64
-b /usr/local/src/pgsql/current/bin/postgres
