PostgreSQL-关系[表]不存在 [英] PostgreSQL - relation [table] does not exist

问题描述

我刚刚创建了一个新用户，我希望可以访问有限数量的公共表。创建用户后，我现在将priv授予了一个公共表。然后，我以该用户身份登录数据库，并尝试在该用户应该能够访问的表上运行SELECT，但是我必须错过某个步骤或做错了什么，因为当我运行查询时，我得到了：

I just created a new user that I want to have access to a limited number of our public tables. The user is created and I granted privs to one public table for now. I then logged into the DB as that user and tried to run a SELECT on the table that the user should be able to get to but I must of missed a step or did something wrong because when I run the query I get:

关系[表]不存在

以下是我按顺序执行的步骤。

Below are the steps I took, in order.

CREATE USER pqb2b WITH PASSWORD 'foo'


 select * from pg_user;
 usename  | usesysid | usecreatedb | usesuper | usecatupd |  passwd   | valuntil | useconfig
 ----------+----------+-------------+----------+-----------+----------+----         |
postgres |       10 | t           | t        | t         | ******** |          | 
 pgb2b   | 17267767 | t           | f        | f         | ******** | infinity |

（1行）

GRANT ALL on b_users to pgb2b;



SELECT
schemaname||'.'||tablename
FROM
pg_tables
WHERE
has_table_privilege (
    'pgb2b',
    schemaname||'.'||tablename,
    'select'
 )
AND
schemaname NOT IN (
    'pg_catalog',
    'information_schema'
 );

public.b_users
(1 row)



~ postgres$ psql -U pgb2b  mydb
psql (9.0.3)
Type "help" for help.

mydb=> select * from b_users;
ERROR:  relation "b_users" does not exist
LINE 1: select * from b_users;

 mydb=> \d+ b_users
 Did not find any relation named "b_users".

推荐答案

即使我向pgb2b用户授予了特权，我忘了为该用户指定用法：

Even though I was granting privileges to my pgb2b user, I forgot to specify usage for that user:

GRANT usage on schema public to pgb2b;

此问题已解决。我发现此帖子关于设置PostgreSQL用户权限非常有帮助。

This fixed the issue. I found this post about setting up PostgreSQL user permissions very helpful.
