PostgreSQL - 关系[table]不存在

Question

我刚刚创建了一个新用户,我希望能够访问有限数量的公共表.用户已创建,我现在授予一个公共表的权限.然后我以该用户身份登录到数据库,并尝试在用户应该能够访问的表上运行SELECT,但我必须错过一个步骤或做错了什么,因为当我运行查询时,我得到:

关系[表]不存在

以下是我按顺序采取的步骤.

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排)

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".

即使我向我的pgb2b用户授予权限,我也忘了为该用户指定用法:

GRANT usage on schema public to pgb2b;

这解决了这个问题.我发现这篇关于设置PostgreSQL用户权限的帖子非常有帮助.
