## DROP SCHEMA

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 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 a schema.

`CASCADE`

 Automatically drop objects (tables, functions, etc.) that are contained in the schema, and in turn all objects that depend on those objects (see [Section 5.14](ddl-depend.html)).

`RESTRICT`

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

## Notes

 Using the `CASCADE` option might make the command remove objects in other schemas besides the one(s) named.

## 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.
