DROP DOMAIN [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
The following description applies both to Postgres-XC and PostgreSQL if not described explicitly.
DROP DOMAIN removes a domain. Only the owner of a domain can remove it.
- Do not throw an error if the domain does not exist. A notice is issued in this case.
- The name (optionally schema-qualified) of an existing domain.
- Automatically drop objects that depend on the domain (such as table columns).
- Refuse to drop the domain if any objects depend on it. This is the default.
To remove the domain box:
DROP DOMAIN box;
This command conforms to the SQL standard, except for the IF EXISTS option, which is a Postgres-XC extension inheritedofrm PostgreSQL.
