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

       --clear-cache Clears the query cache.

       -d

       --debug Print lots of debug messages.

       -f path

       -F path

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