Hemny 75b48e5d5d 备机连接可以走非HA端口，根据配置中的连接信息决定 2021-07-02 17:38:25 +08:00
Hemny 0cd2b0be96 修复 使用replication协议连接监听端口后,数据库stop失败的问题 
openGauss中，replication协议不能用线程池的线程。
如果数据库启用了线程池，并且出现用户操作失误使用了replication协议工具连接监听端口，连接失败后造成工作线程直接退出，引起gs_ctl stop停库失败。

现在直接在连接数据库时限制如果线程池模式下，replication工具只能通过HA端口连接数据库。

LiHeng f295a72b65 support cascade standby 
We support cascade standby now, a cascade standby will get WAL from
a standby asynchronously. To support flexible deployment, we add a
new GUC available_zone to identify the available zone of a cascade
standby, which will try to connect a standby in same available zone.

Users can use utility gs_ctl for failover and switchover. A cascade
standby will be promoted to be a standby when failover or switchover,
while a standby will be demoted to be a cascade standby after switchover.
