2015-06-13 02:31:49 DEBUG: pid 3235: pool_config: empty system_db_hostname, use PostgreSQL's default unix socket path (/var/run/postgresql)
pgpool-II version 3.3.4 (tokakiboshi),
  A generic connection pool/replication/load balance server for PostgreSQL

Usage:
  pgpool [ -c] [ -f CONFIG_FILE ] [ -F PCP_CONFIG_FILE ] [ -a HBA_CONFIG_FILE ]
         [ -n ] [ -D ] [ -d ]
  pgpool [ -f CONFIG_FILE ] [ -F PCP_CONFIG_FILE ] [ -a HBA_CONFIG_FILE ]
         [ -m SHUTDOWN-MODE ] stop
  pgpool [ -f CONFIG_FILE ] [ -F PCP_CONFIG_FILE ] [ -a HBA_CONFIG_FILE ] reload

Common options:
  -a, --hba-file=HBA_CONFIG_FILE
                      Sets the path to the pool_hba.conf configuration file
                      (default: /etc/pgpool2/pool_hba.conf)
  -f, --config-file=CONFIG_FILE
                      Sets the path to the pgpool.conf configuration file
                      (default: /etc/pgpool2/pgpool.conf)
  -F, --pcp-file=PCP_CONFIG_FILE
                      Sets the path to the pcp.conf configuration file
                      (default: /etc/pgpool2/pcp.conf)
  -h, --help          Prints this help

Start options:
  -c, --clear         Clears query cache (enable_query_cache must be on)
  -C, --clear-oidmaps Clears query cache oidmaps when memqcache_method is memcached
                      (If shmem, discards whenever pgpool starts.)
  -n, --dont-detach   Don't run in daemon mode, does not detach control tty
  -D, --discard-status Discard pgpool_status file and do not restore previous status
  -d, --debug         Debug mode

Stop options:
  -m, --mode=SHUTDOWN-MODE
                      Can be "smart", "fast", or "immediate"

Shutdown modes are:
  smart       quit after all clients have disconnected
  fast        quit directly, with proper shutdown
  immediate   the same mode as fast
