# DROP TYPE

## Name

DROP TYPE -- remove a data type

## Synopsis

    DROP TYPE name [, ...] [ CASCADE | RESTRICT ]

## Description

`DROP TYPE` will remove a user-defined data type. Only the owner of a type can remove it.

## Parameters

name

  The name (optionally schema-qualified) of the data type to remove.

CASCADE

  Automatically drop objects that depend on the type (such as table columns, functions, operators).

RESTRICT

  Refuse to drop the type if any objects depend on it. This is the default.

## Examples

To remove the data type `box`:

    DROP TYPE box;

## Compatibility

This command is similar to the corresponding command in the SQL standard, but note that the `CREATE TYPE` command and the data type extension mechanisms in PostgreSQL differ from the SQL standard.
