STARTING PGPOOL-II MAIN SERVER

       Here are options for the start mode.

       -d
       --debug
           Run Pgpool-II in debug mode. Lots of debug messages are produced.

       -C
       --clear-oidmaps
           Clear query cache oidmaps when memqcache_method is memcached.

           If memqcache_method is shmem, Pgpool-II always discards oidmaps at the start-up time.
           So this option is not necessary.

       -D
       --discard-status
           Discard pgpool_status file and do not restore previous status.

           are specified, Pgpool-II immediately stops itself without waiting for all clients are
