| <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"><span class="application">initdb</span></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. | |
| 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. | |
| 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="25.3. Log File Maintenance">Section 25.3</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. | |
