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).
