DROP TYPE

    Description

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

    IF EXISTS

    Do not throw an error if the type does not exist. A notice is issued in this case.

    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).

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

    Examples

    Remove the data type ;

    This command is similar to the corresponding command in the SQL standard, apart from the option, which is a Greenplum Database extension. But note that the command and the data type extension mechanisms in Greenplum Database differ from the SQL standard.
