Title: DROP LANGUAGE Author: The PostgreSQL Global Development Group Generator: DocBook XSL Stylesheets v1.79.1 <http://docbook.sf.net/> Date: 2017 Manual: PostgreSQL 9.6.5 Documentation Source: PostgreSQL 9.6.5 Language: English
NAMEDROP_LANGUAGE - remove a procedural language
DROP [ PROCEDURAL ] LANGUAGE [ IF EXISTS ] name [ CASCADE | RESTRICT ]
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.
As of PostgreSQL 9.1, most procedural languages have been made into lqextensionsrq, and should therefore be removed with DROP EXTENSION (DROP_EXTENSION(7)) not DROP LANGUAGE.
- Do not throw an error if the language does not exist. A notice is issued in this case.
- The name of an existing procedural language. For backward compatibility, the name can be enclosed by single quotes.
- Automatically drop objects that depend on the language (such as functions in the language).
- Refuse to drop the language if any objects depend on it. This is the default.
This command removes the procedural language plsample:
DROP LANGUAGE plsample;
There is no DROP LANGUAGE statement in the SQL standard.
