## NAME
       DROP_DOMAIN - remove a domain

## SYNOPSIS
       DROP DOMAIN [ IF EXISTS ] _name_ [, ...] [ CASCADE | RESTRICT ]

## DESCRIPTION
       **DROP** **DOMAIN** removes a domain. Only the owner of a domain can remove it.

## PARAMETERS
       IF EXISTS
           Do not throw an error if the domain does not exist. A notice is issued in this case.

       _name_
           The name (optionally schema-qualified) of an existing domain.

       CASCADE
           Automatically drop objects that depend on the domain (such as table columns), and in turn
           all objects that depend on those objects (see Section 5.14).

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

## EXAMPLES
       To remove the domain box:

           DROP DOMAIN box;

## COMPATIBILITY
       This command conforms to the SQL standard, except for the IF EXISTS option, which is a
       PostgreSQL extension.
