37.37. role_table_grants #

视图 role_table_grants 识别对授予者或被授予者为当前启用角色的表或视图授予的所有权限。可以在 table_privileges 下找到更多信息。此视图与 table_privileges 唯一的有效区别在于，此视图省略了通过对 PUBLIC 授予而可以直接访问当前用户的表。

The view role_table_grants identifies all privileges granted on tables or views where the grantor or grantee is a currently enabled role. Further information can be found under table_privileges. The only effective difference between this view and table_privileges is that this view omits tables that have been made accessible to the current user by way of a grant to PUBLIC.
