pg配置流复制后,citus如法添加节点

postgres=# SELECT * from citus_add_node('192.168.174.16', 5432,1,'primary');
错误: 在恢复操作的过程中不能在数据库对象上获取锁模式ExclusiveLock
提示: 在恢复操作期间只有在数据对象上获取RowExclusiveLock或者更低级别的锁。

Start by reproducing the SELECT citus_add_node('192.168.174.16', 5432, 1, 'primary') command while PostgreSQL streaming replication is configured. Read the Citus node-management and PostgreSQL recovery-lock documentation to determine whether this is an expected limitation or a defect. Done means the behavior and any required documentation change are clearly established.
