Synopsis

DROP DOMAIN [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

Parameters

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

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.
