postgres只读用户不工作

Question

我有运行数据库的 Postgresql 9.2，现在尝试创建一个只读用户。我遵循了这些描述：

ERROR: permission denied for relation tablename on Postgres while trying a SELECT as a readonly user

How do you create a read-only user in PostgreSQL?

基本上我做了以下事情：

jbossmanager=# CREATE USER jbcust  WITH ENCRYPTED PASSWORD '#######';
CREATE ROLE
jbossmanager=# GRANT USAGE ON SCHEMA jbossmanager to jbcust;
GRANT
jbossmanager=# ALTER DEFAULT PRIVILEGES IN SCHEMA jbossmanager GRANT SELECT ON TABLES TO jbcust;
ALTER DEFAULT PRIVILEGES
jbossmanager=# GRANT CONNECT ON DATABASE jbossmanager to jbcust;
GRANT
jbossmanager=# GRANT SELECT ON ALL SEQUENCES IN SCHEMA jbossmanager TO jbcust;
GRANT
jbossmanager=# GRANT SELECT ON ALL TABLES IN SCHEMA jbossmanager TO jbcust;
GRANT

在此之后，“\l”显示如下：

jbossmanager=# \l
                                     List of databases
 Name     |    Owner     | Encoding |   Collate   |    Ctype    |       Access privileges
--------------+--------------+----------+-------------+-------------+-------------------------------
 jbossmanager | jbossmanager | UTF8     | en_US.UTF-8 | en_US.UTF-8 | =Tc/jbossmanager             +
          |              |          |             |             | jbossmanager=CTc/jbossmanager+
          |              |          |             |             | jbcust=c/jbossmanager

这对我来说看起来不错，该数据库/模式中的表列表也很好：

jbossmanager=# \dp+
                                                   Access privileges
    Schema    |             Name              |   Type   |         Access privileges         | Column access privileges
--------------+-------------------------------+----------+-----------------------------------+--------------------------
 jbossmanager | env_server_standalone_info    | table    | jbossmanager=arwdDxt/jbossmanager+|
              |                               |          | jbcust=r/jbossmanager             |

但是现在当我作为这个 jbcust 用户连接到数据库并尝试时：

#psql -d jbossmanager -U jbcust -h 127.0.0.1
Password for user jbcust:
psql (9.2.4)
Type "help" for help.

jbossmanager=> \dp+
                          Access privileges
 Schema | Name | Type | Access privileges | Column access privileges
--------+------+------+-------------------+--------------------------
(0 rows)

我不知道哪里出了问题或缺少了什么。

非常感谢您的帮助！

Answer 1

与只读用户连接时我没有看到任何架构的原因是没有设置此用户的默认架构。

之后：

ALTER USER jbcust SET search_path = jbossmanager;

效果很好。
