DROP SERVER

删除服务器——移除一个外部服务器描述符

DROP SERVER — remove a foreign server descriptor

DROP SERVER [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

DROP SERVER 移除一个已存在的外部服务器描述符。要执行此命令，当前用户必须是服务器所有者。

DROP SERVER removes an existing foreign server descriptor. To execute this command, the current user must be the owner of the server.

IF EXISTS
- Do not throw an error if the server does not exist. A notice is issued in this case.
name
- The name of an existing server.
CASCADE
- Automatically drop objects that depend on the server (such as user mappings), and in turn all objects that depend on those objects (see Section 5.14).
RESTRICT
- Refuse to drop the server if any objects depend on it. This is the default.

如果存在服务器 foo ，则将其删除：

Drop a server foo if it exists:

DROP SERVER IF EXISTS foo;

DROP SERVER 符合 ISO/IEC 9075-9（SQL/MED）。 IF EXISTS 子句是 PostgreSQL 扩展。

DROP SERVER conforms to ISO/IEC 9075-9 (SQL/MED). The IF EXISTS clause is a PostgreSQL extension.
