Removes a schema.

Synopsis

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

Description

DROP SCHEMA removes schemas from the database.

A schema can be dropped only by its owner or a superuser. Note that the owner can drop the schema (and thereby all contained objects) even if they do 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 the schema to remove.

CASCADE

Automatically drop objects (tables, functions, etc.) that are contained in the schema, and in turn all objects that depend on those objects.

RESTRICT

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

Notes

Using the CASCADE option may result in the command removing objects in other schemas besides the one(s) named.

Examples

Remove the 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. Also, the IF EXISTS option is a WarehousePG extension.
