DROP FOREIGN TABLE
DROP FOREIGN TABLE — remove a foreign table
Synopsis
DROP FOREIGN TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
Description
DROP FOREIGN TABLE removes a foreign table. Only the owner of a foreign table can remove it. 
Parameters
- IF EXISTS
- Do not throw an error if the foreign table does not exist. A notice is issued in this case. 
- name
- The name (optionally schema-qualified) of the foreign table to drop. 
- CASCADE
- Automatically drop objects that depend on the foreign table (such as views), and in turn all objects that depend on those objects (see Section 5.14). 
- RESTRICT
- Refuse to drop the foreign table if any objects depend on it. This is the default. 
Examples
 To destroy two foreign tables, films and distributors: 
DROP FOREIGN TABLE films, distributors;
Compatibility
 This command conforms to the ISO/IEC 9075-9 (SQL/MED), except that the standard only allows one foreign table to be dropped per command, and apart from the IF EXISTS option, which is a Postgres Pro extension.
