主库上的vip漂移到备库后,就不能用vip地址及备库上pool的端口号去连接数据库了

环境信息:

    centos操作系统一主一备.
    数据库版本:9.4.5
    pool版本:3.4

问题描述:主库上的vip漂移到备库后,就不能用vip地址及备库上pool的端口号去连接数据库了.

错误现象:

    [srdb@localhost ~]$ psql -p 1975
    sql: server closed the connection unexpectedly
    This probably means the server terminated abnormally
    before or while processing the request.
