Question

我在从PSQL中选择数据库时遇到问题。这是我感兴趣的表格的输出。有人可以为我解读访问权限吗？我知道arwdRxt意味着追加，读取，写入等等......语法让我感到困惑，在权限列中斜杠和等于究竟是什么意思？如果我的问题不明确，请告诉我。

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

Answer 1

在[docs]中有详细描述。 =之前的东西是谁拥有这些权限，/是谁是谁授予了这些权限。
