NAME

       SHOW_POOL_NODES - sends back a list of all configured nodes

SYNOPSIS

          SHOW POOL_NODES

DESCRIPTION

       SHOW POOL_NODES displays the node id, the hostname, the port, the status, the weight (only
       meaningful if you use the load balancing mode), the role, the SELECT query counts issued
       to each backend, whether each node is the load balance node or not, the replication delay
       (only if in streaming replication mode) and last status change time. In addition to this
       replication state and sync state are shown for standby nodes in Pgpool-II 4.1 or after.
       Also actual node status and node role are shown in Pgpool-II 4.3 or after.

       The possible values in the status column are explained in the pcp_node_info(1) reference.

       If the hostname is something like "/tmp", that means Pgpool-II is connecting to backend by
       using UNIX domain sockets. The SELECT count does not include internal queries used by
       Pgpool-II. Also the counters are reset to zero upon starting up of Pgpool-II. The last
       status change time is initially set to the time Pgpool-II starts. After that whenever
       "status" or "role" is changed, it is updated.

       Here is an example session:

           test=# show pool_nodes;
            node_id | hostname | port  | status | pg_status | lb_weight |  role   | pg_role | select_cnt | load_balance_node | replication_delay | replication_state | replication_sync_state | last_status_change
