postgresql - 理解 PSQL 的 \dp 和 \z 的输出

Question

我无法从 PSQL 中的数据库中进行选择。这是我感兴趣的表的输出。有人可以为我破译访问权限吗？我知道这arwdRxt意味着追加、读取、写入等......语法让我感到困惑，访问权限列中的斜杠和等号到底是什么意思？如果我的问题不清楚，请告诉我。

                    Access privileges
 schema |     name      | type |    access privileges    
--------+---------------+------+-------------------------
 public | table_name    | view | amazonuser=arwdRxt/amazonuser+
        |               |      | readonly=r/amazonuser

Answer 1

它在docs中有详细描述。= 之前的东西是谁拥有这些权限，/ 之后的东西是谁授予了这些权限。
