DROP SERVER - remove a foreign server descriptor

DROP SERVER [ IF EXISTS ] servername [ CASCADE | RESTRICT ]

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.
servername: The name of an existing server.
CASCADE: Automatically drop objects that depend on the server (such as user mappings).
RESTRICT: Refuse to drop the server if any objects depend on it. This is the default.

Drop a server foo if it exists:

DROP SERVER IF EXISTS foo;

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