当pgpool两节点状态均显示standby时的解决方法

两行代码：

pgpool stop
pgpool -C -D

执行前：

highgo=# show pool_nodes;
 node_id | hostname | port | status | lb_weight |  role   | select_cnt | load_balance_node | replication_delay 
---------+----------+------+--------+-----------+---------+------------+-------------------+-------------------
 0       | db1      | 5866 | up     | 0.500000  | standby | 0          | true              | 0
 1       | db2      | 5866 | down   | 0.500000  | standby | 0          | false             | 0
(2 rows)

执行后：

highgo=# show pool_nodes;
 node_id | hostname | port | status | lb_weight |  role   | select_cnt | load_balance_node | replication_delay 
---------+----------+------+--------+-----------+---------+------------+-------------------+-------------------
 0       | db1      | 5866 | up     | 0.500000  | standby | 0          | false             | 0
 1       | db2      | 5866 | up     | 0.500000  | primary | 0          | true              | 0
(2 rows)
