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. SEE ALSO
ALTER SCHEMA (ALTER_SCHEMA(7)), CREATE SCHEMA (CREATE_SCHEMA(7)) PostgreSQL 9.2.7 2014-02-17 DROP SCHEMA(7)
