37.58. udt_privileges #
视图 _udt_privileges_标识了当前启用的角色或当前启用的角色授予给用户定义类型的 _USAGE_权限。对于类型、授权人和被授权人的每个组合，都有一个行。此视图仅显示复合类型（有关原因，请参阅 Section 37.60）；有关域权限，请参阅 Section 37.59。
The view udt_privileges identifies USAGE privileges granted on user-defined types to a currently enabled role or by a currently enabled role. There is one row for each combination of type, grantor, and grantee. This view shows only composite types (see under Section 37.60 for why); see Section 37.59 for domain privileges.
