DROP FOREIGN DATA WRAPPER removes an existing foreign-data wrapper. To execute this command, the current user must be the owner of the foreign-data wrapper.
- IF EXISTS
Do not throw an error if the foreign-data wrapper does not exist. A notice is issued in this case.
The name of an existing foreign-data wrapper.
Automatically drop objects that depend on the foreign-data wrapper (such as foreign tables and servers), and in turn all objects that depend on those objects (see Section 5.13).
Refuse to drop the foreign-data wrapper if any objects depend on it. This is the default.
DROP FOREIGN DATA WRAPPER conforms to ISO/IEC 9075-9 (SQL/MED). The IF EXISTS clause is a PostgreSQL extension.
