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 disallows new connections, then waits + for all existing 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. + </p></div><div class="refsect1" id="APP-PG-CTL-OPTIONS"><h2>Options</h2><div class="variablelist"><dl class="variablelist"><dt><span class="term"><code class="option">-c</code><br /></span><span class="term"><code class="option">--core-files</code></span></dt><dd><p> + Attempt to allow server crashes to produce core files, on platforms + where this is possible, by lifting any soft resource limit placed on + core files. + This is useful in debugging or diagnosing problems by allowing a + stack trace to be obtained from a failed server process. + </p></dd><dt><span class="term"><code class="option">-D <em class="replaceable"><code>datadir</code></em></code><br /></span><span class="term"><code class="option">--pgdata=<em class="replaceable"><code>datadir</code></em></code></span></dt><dd><p> + Specifies the file system location of the database configuration files.
