PG_CTLCLUSTER(8)       Debian PostgreSQL infrastructure	      PG_CTLCLUSTER(8)

NAME
       pg_ctlcluster - start/stop/restart/reload a PostgreSQL cluster

SYNOPSIS
       pg_ctlcluster [options] cluster-version cluster-name action -- [pg_ctl
       options]

       where action = start|stop|restart|reload

DESCRIPTION
       This program controls the postmaster server for a particular cluster.
       It essentially wraps the pg_ctl(1) command. It determines the cluster
       version and data path and calls the right version of pg_ctl with
       appropriate configuration parameters and paths.

       You have to start this program as the user who owns the database
       cluster or as root.

ACTIONS
       start
	   A log file for this specific cluster is created if it does not
	   exist yet (by default, /var/log/postgresql/postgresql-cluster-
	   version-cluster-name.log), and a PostreSQL server process
	   (postmaster(1)) is started on it. Exits with 0 on success, with 2
	   if the server is already running, and with 1 on other failure
	   conditions.

       stop
	   Stops the postmaster(1) server of the given cluster. By default,
	   "smart" mode is used, which waits until all clients disconnected.

	   With the --force option the "fast" mode is used which rolls back
	   all active transactions, disconnects clients immediately and thus
	   shuts down cleanly. If that does not work, shutdown is attempted
	   again in "immediate" mode, which can leave the cluster in an
	   inconsistent state and thus will lead to a recovery run at the next
	   start. If this still does not help, the postmaster process is
	   killed.  Exits with 0 on success, with 2 if the server is not
	   running, and with 1 on other failure conditions. This mode should
	   only be used when the machine is about to be shut down.

       restart
	   Stops the server if it is running and starts it (again).

       reload
	   Causes the configuration files to be re-read without a full
	   shutdown of the server.

OPTIONS
       -o option
	   Pass given option as command line option to the postmaster process.
	   It is possible to specify -o multiple times. See postmaster(1) for
	   a description of valid options.

       pg_ctl options
	   Pass given pg_ctl options as command line options to pg_ctl. See
	   pg_ctl(1) for a description of valid options.

FILES
       /etc/postgresql/cluster-version/cluster-name/pg_ctl.options
	   This configuration file contains cluster specific options to be
	   passed to pg_ctl(1).
