DROP LANGUAGE
Name
DROP LANGUAGE -- remove a procedural languageSynopsis
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).
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.
