DROP 
SCHEMA(7)						  PostgreSQL 9.2.7 Documentation					    DROP SCHEMA(7)

NAME
       DROP_SCHEMA - remove a schema

SYNOPSIS
       DROP SCHEMA [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

DESCRIPTION
       DROP SCHEMA removes schemas from the database.

       A schema can only be dropped by its owner or a superuser. Note that the owner can drop the schema (and thereby all contained objects) even
       if he does not own some of the objects within the schema.

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

       name
	   The name of a schema.

       CASCADE
	   Automatically drop objects (tables, functions, etc.) that are contained in the schema.

       RESTRICT
	   Refuse to drop the schema if it contains any objects. This is the default.

EXAMPLES
       To remove schema mystuff from the database, along with everything it contains:

	   DROP SCHEMA mystuff CASCADE;

COMPATIBILITY
       DROP SCHEMA is fully conforming with the SQL standard, except that the standard only allows one schema to be dropped per command, and apart
       from the IF EXISTS option, which is a PostgreSQL extension.
