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 Dependency Tracking).
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 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 PostgreSQL extension.
