- <span class="application">pg_ctl</span> is a utility for initializing a
- <span class="productname">PostgreSQL</span> database cluster, starting,
- stopping, or restarting the <span class="productname">PostgreSQL</span>
- database server (<a class="xref" href="app-postgres.html" title="postgres"><span class="refentrytitle"><span class="application">postgres</span></span></a>), or displaying the
- status of a running server. Although the server can be started
- manually, <span class="application">pg_ctl</span> encapsulates tasks such
- as redirecting log output and properly detaching from the terminal
- and process group. It also provides convenient options for
- controlled shutdown.
- </p><p>
- The <code class="option">init</code> or <code class="option">initdb</code> mode creates a new
- <span class="productname">PostgreSQL</span> database cluster, that is,
- a collection of databases that will be managed by a single
- server instance. This mode invokes the <code class="command">initdb</code>
- command. See <a class="xref" href="app-initdb.html" title="initdb"><span class="refentrytitle">initdb</span></a> for details.
- </p><p>
- <code class="option">start</code> mode launches a new server. The
- server is started in the background, and its standard input is attached
- to <code class="filename">/dev/null</code> (or <code class="literal">nul</code> on Windows).
- On Unix-like systems, by default, the server's standard output and
- standard error are sent to <span class="application">pg_ctl</span>'s
- standard output (not standard error). The standard output of
- <span class="application">pg_ctl</span> should then be redirected to a
- file or piped to another process such as a log rotating program
- like <span class="application">rotatelogs</span>; otherwise <code class="command">postgres</code>
- will write its output to the controlling terminal (from the
- background) and will not leave the shell's process group. On
- Windows, by default the server's standard output and standard error
- are sent to the terminal. These default behaviors can be changed
- by using <code class="option">-l</code> to append the server's output to a log file.
- Use of either <code class="option">-l</code> or output redirection is recommended.
- </p><p>
- <code class="option">stop</code> mode shuts down the server that is running in
- the specified data directory. Three different
- shutdown methods can be selected with the <code class="option">-m</code>
- option. <span class="quote">“<span class="quote">Smart</span>”</span> mode waits for all active
- clients to disconnect and any online backup to finish.
- If the server is in hot standby, recovery and streaming replication
- will be terminated once all clients have disconnected.
- <span class="quote">“<span class="quote">Fast</span>”</span> mode (the default) does not wait for clients to disconnect and
- will terminate an online backup in progress. All active transactions are
- rolled back and clients are forcibly disconnected, then the
- server is shut down. <span class="quote">“<span class="quote">Immediate</span>”</span> mode will abort
- all server processes immediately, without a clean shutdown. This choice
- will lead to a crash-recovery cycle during the next server start.
- </p><p>
- <code class="option">restart</code> mode effectively executes a stop followed
- by a start. This allows changing the <code class="command">postgres</code>
- command-line options, or changing configuration-file options that
- cannot be changed without restarting the server.
- If relative paths were used on the command line during server
- start, <code class="option">restart</code> might fail unless
- <span class="application">pg_ctl</span> is executed in the same current
- directory as it was during server start.
- </p><p>
- <code class="option">reload</code> mode simply sends the
- <code class="command">postgres</code> server process a <span class="systemitem">SIGHUP</span>
- signal, causing it to reread its configuration files
- (<code class="filename">postgresql.conf</code>,
- <code class="filename">pg_hba.conf</code>, etc.). This allows changing
- configuration-file options that do not require a full server restart
- to take effect.
- </p><p>
- <code class="option">status</code> mode checks whether a server is running in
- the specified data directory. If it is, the server's <acronym class="acronym">PID</acronym>
- and the command line options that were used to invoke it are displayed.
- If the server is not running, <span class="application">pg_ctl</span> returns
- an exit status of 3. If an accessible data directory is not
- specified, <span class="application">pg_ctl</span> returns an exit status of 4.
- </p><p>
- <code class="option">promote</code> mode commands the standby server that is
- running in the specified data directory to end standby mode
- and begin read-write operations.
- </p><p>
- <code class="option">logrotate</code> mode rotates the server log file.
- For details on how to use this mode with external log rotation tools, see
- <a class="xref" href="logfile-maintenance.html" title="24.3. Log File Maintenance">Section 24.3</a>.
- </p><p>
- <code class="option">kill</code> mode sends a signal to a specified process.
- This is primarily valuable on <span class="productname">Microsoft Windows</span>
- which does not have a built-in <span class="application">kill</span> command. Use
- <code class="literal">--help</code> to see a list of supported signal names.
- </p><p>
- <code class="option">register</code> mode registers the <span class="productname">PostgreSQL</span>
- server as a system service on <span class="productname">Microsoft Windows</span>.
- The <code class="option">-S</code> option allows selection of service start type,
- either <span class="quote">“<span class="quote">auto</span>”</span> (start service automatically on system startup)
- or <span class="quote">“<span class="quote">demand</span>”</span> (start service on demand).
- </p><p>
- <code class="option">unregister</code> mode unregisters a system service
- on <span class="productname">Microsoft Windows</span>. This undoes the effects of the
- <code class="option">register</code> command.

- When waiting, <code class="command">pg_ctl</code> repeatedly checks the

- </p><p>
- If the operation does not complete within the timeout (see

- </p><pre class="screen">
- <code class="prompt">$</code> <strong class="userinput"><code>pg_ctl start</code></strong>
- </pre><p>
- </p><p>

- To stop the server, use:
- </p><pre class="screen">
- <code class="prompt">$</code> <strong class="userinput"><code>pg_ctl stop</code></strong>
