DROP SCHEMA
Function
DROP SCHEMA deletes a schema from the current database.
Precautions
Only the owner of a schema or a system administrator has the DROP SCHEMA permission.
Syntax
DROP SCHEMA [ IF EXISTS ] schema_name [, ...] [ CASCADE | RESTRICT ];
Parameter Description
IF EXISTS
Reports a notice instead of an error if the specified schema does not exist.
schema_name
Specifies the name of the schema to be deleted.
Value range: an existing schema name
CASCADE | RESTRICT
- CASCADE: automatically deletes all the objects contained in the schema.
- RESTRICT: refuses to delete the schema if the schema contains objects. This is the default action.
NOTICE:
Schemas beginning with pg_temp or pg_toast_temp are for internal use. Do not delete them. Otherwise, unexpected consequences may be incurred.

The schema currently being used cannot be deleted. To delete it, switch to another schema first.
