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
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" 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.
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.
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.
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).
