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|promote

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" shutdown mode is used, which
           waits until all clients disconnected.

       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.

       promote
           Commands a running standby server to exit recovery and begin read-write operations.

OPTIONS

       -f|--force
           For stop and restart, 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.

       -m|--mode [smart|fast|immediate]
           Shutdown mode to use for stop and restart actions, default is smart.  See pg_ctl(1) for
           documentation.

       -o|--options 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.conf
           This configuration file contains cluster specific options to be passed to pg_ctl(1).

       /etc/postgresql/cluster-version/cluster-name/start.conf
           This configuration file controls the start/stop behavior of the cluster. See section "STARTUP
           CONTROL" in pg_createcluster(8) for details.
