NAME

       pgpool - PostgreSQL connection pool daemon

SYNOPSIS

       pgpool [ -c] [ -f config_file ] [ -F pcp_config_file ] [ -a hba_file ] [ -n ] [ -d ]

       pgpool [ -f config_file ] [ -F pcp_config_file ] [ -a hba_file ] [ -m {s[mart]|f[ast]|i[mmediate]} ] stop

       pgpool [ -f config_file ] [ -F pcp_config_file ] [ -a hba_file ] reload

DESCRIPTION

       pgpool is a connection pool server for PostgreSQL.  pgpool runs between PostgreSQL's client and server.	Any PostgreSQL client can connect
       to pgpool as if it's a real PostgreSQL server.  pgpool caches the connection to the PostgreSQL server to reduce the overhead involved in
       establishing the connection to it.

       pgpool can also be used with two PostgreSQL servers for fail over purposes.  If the first server goes down, pgpool will automatically
       switch to the secondary server.

       pgpool is typically started and stopped via system initialization scripts.

INVOCATION

       pgpool [ options... ]
	      Starts as a daemon in the background (unless -n is given).

       pgpool [ options... ] stop
	      Shutdown.

       pgpool [ options... ] reload
	      Reloads the configuration.

OPTIONS

       -a path

       --hba-file path Sets the path to the pool_hba.conf configuration file (default: /etc/pgpool2/pgpool_hba.conf).

       -c

       --clear-cache Clears the query cache.

       -d

       --debug Print lots of debug messages.

       -f path

       --config-file path Sets the path to the pgpool.conf configuration file (default: /etc/pgpool2/pgpool.conf).

       -F path

       --pcp-config-file path Sets the path to the pcp.conf configuration file (default: /etc/pgpool2/pcp.conf).

       -h

       --help Print a help message and exit.

       -m mode

       --mode mode Shutdown mode: smart, fast, or immediate.

       -n

       --no-daemon Foreground mode.  Error messages go to stdout or stderr, which could be piped out to log processors such as logger(1) or
       rotatelogs(8).  To daemonize, explicitly invoke pgpool in background.

       -v

       --version Print version and exit.

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" 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.

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

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