DROP LANGUAGE

Name

DROP LANGUAGE -- remove a procedural language

Synopsis

DROP [ PROCEDURAL ] LANGUAGE [ IF EXISTS ] name [ CASCADE | RESTRICT ]

Description

DROP LANGUAGE removes the definition of a previously registered procedural language. You must be a superuser or the owner of the language to use DROP LANGUAGE.

Note: As of PostgreSQL 9.1, most procedural languages have been made into "extensions", and should therefore be removed with DROP EXTENSION not DROP LANGUAGE.

Parameters

IF EXISTS: Do not throw an error if the language does not exist. A notice is issued in this case.
name: The name of an existing procedural language. For backward compatibility, the name can be enclosed by single quotes.
CASCADE: Automatically drop objects that depend on the language (such as functions in the language), and in turn all objects that depend on those objects (see Section 5.13).
RESTRICT: Refuse to drop the language if any objects depend on it. This is the default.

Examples

This command removes the procedural language plsample:

DROP LANGUAGE plsample;

Compatibility

There is no DROP LANGUAGE statement in the SQL standard.
