作为对 CREATE_REPLICATION_SLOT 命令的响应，服务器将发送一个包含以下字段的单行结果集：slot_name (text)：新创建的复制插槽的名称。consistent_point (text)：插槽变得一致的 WAL 位置。这是可以在此复制插槽上启动流的最早位置。snapshot_name (text)：命令导出的快照的标识符。在该连接上执行新命令或关闭复制...
• CREATE_REPLICATION_SLOT slot_name {PHYSICAL | LOGICAL output_plugin}:这将创建一个复制槽(物理或逻辑)。在逻辑复制槽的情况下,用于格式化复制槽返回的数据的输出插件是强制性的。This creates a replication slot (physical or logical). In the case of a logical replication slot, an output plugin ...
SELECT * FROM pg_create_physical_replication_slot('my_slot'); 1. 这条命令在主库上创建了一个名为my_slot的物理复制槽。 查看复制槽状态: SELECT * FROM pg_replication_slots; 1. 这条命令可以查看所有复制槽的状态,包括我们刚刚创建的my_slot。
