TYPE(7)						  PostgreSQL 9.2.7 Documentation					      DROP TYPE(7)

NAME

       DROP_TYPE - remove a data type

SYNOPSIS

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

DESCRIPTION

       DROP TYPE removes a user-defined data type. Only the owner of a type can remove it.

PARAMETERS

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

       name
	   The name (optionally schema-qualified) of the data type to remove.

       CASCADE
	   Automatically drop objects that depend on the type (such as table columns, functions, operators).

       RESTRICT
	   Refuse to drop the type if any objects depend on it. This is the default.

EXAMPLES

       To remove the data type box:

	   DROP TYPE box;

COMPATIBILITY

       This command is similar to the corresponding command in the SQL standard, apart from the IF EXISTS option, which is a PostgreSQL extension.
       But note that much of the CREATE TYPE command and the data type extension mechanisms in PostgreSQL differ from 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.
