DROP LANGUAGE
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.
