LANGUAGE(7)					  PostgreSQL 9.2.7 Documentation					  DROP LANGUAGE(7)

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
	   (DROP_EXTENSION(7)) 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.

NAME

       DROP_EXTENSION - remove an extension

SYNOPSIS

       DROP EXTENSION [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP EXTENSION removes extensions from the database. Dropping an extension causes its component objects to be dropped as well.

       You must own the extension to use DROP EXTENSION.

PARAMETERS

       IF EXISTS
	   Do not throw an error if the extension does not exist. A notice is issued in this case.

       name
	   The name of an installed extension.

       CASCADE
	   Automatically drop objects that depend on the extension.

       RESTRICT
	   Refuse to drop the extension if any objects depend on it (other than its own member objects and other extensions listed in the same
	   DROP command). This is the default.

EXAMPLES

       To remove the extension hstore from the current database:

	   DROP EXTENSION hstore;

       This command will fail if any of hstore's objects are in use in the database, for example if any tables have columns of the hstore type.
       Add the CASCADE option to forcibly remove those dependent objects as well.

COMPATIBILITY

       DROP EXTENSION is a PostgreSQL extension.
