NAME

       pgpool - PostgreSQL connection pool daemon

SYNOPSIS

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

       --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:
