37.39. role_usage_grants #
视图 role_usage_grants 标识授予各种对象（其中授予者或接受者是当前启用的角色）的 USAGE 权限。更多信息，请参见 usage_privileges。此视图与 usage_privileges 之间的唯一有效差异是此视图省略了通过授予 PUBLIC 而对当前用户可访问的对象。
The view role_usage_grants identifies USAGE privileges granted on various kinds of objects where the grantor or grantee is a currently enabled role. Further information can be found under usage_privileges. The only effective difference between this view and usage_privileges is that this view omits objects that have been made accessible to the current user by way of a grant to PUBLIC.
