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 5.13).

       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.
