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

- 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

Examples
 Drop a server foo if it exists: 
DROP SERVER IF EXISTS foo;
