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


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

       where action = start|stop|restart|reload|promote


       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.


           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

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

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

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

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


           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.


           This configuration file contains cluster specific options to be
           passed to pg_ctl(1).

           This configuration file controls the start/stop behavior of the
           cluster. See section "STARTUP CONTROL" in pg_createcluster(8) for


       pg_createcluster(8), pg_ctl(1), pg_wrapper(1), pg_lsclusters(1),
