【问题描述】：

我正在与带有组、模式、默认权限的 Redshit 授权作斗争。当我尝试使用 HAS_TABLE_PRIVILEGE 检查一切是否正确时

select tablename, 
   HAS_TABLE_PRIVILEGE('analyst', tablename, 'select') as select,
   HAS_TABLE_PRIVILEGE('analyst', tablename, 'insert') as insert,
   HAS_TABLE_PRIVILEGE('analyst', tablename, 'update') as update,
   HAS_TABLE_PRIVILEGE('analyst', tablename, 'delete') as delete, 
   HAS_TABLE_PRIVILEGE('analyst', tablename, 'references') as references 
from pg_tables
where schemaname='datalab'
order by tablename

我明白了：

An error occurred when executing the SQL command:
select tablename, 
   HAS_TABLE_PRIVILEGE('analyst', tablename, 'select') as select,
   HAS_TABLE_PRIVILEGE('analyst', tablena...

[Amazon](500310) Invalid operation: relation "dss__transaction" does not exist;

Execution time: 0.2s
1 statement failed.

这里到底发生了什么？

我试过这个，但查询来自pg_tables 的第一个结果失败。就我而言，这是因为我需要明确说明每个表所在的架构。这对我有用：

WITH cte AS 
(
SELECT schemaname+'.'+tablename AS table_name
FROM pg_tables
WHERE schemaname = 'datalab'
)
SELECT table_name, 
   HAS_TABLE_PRIVILEGE('analyst', table_name, 'select') AS select,
   HAS_TABLE_PRIVILEGE('analyst', table_name, 'insert') AS insert,
   HAS_TABLE_PRIVILEGE('analyst', table_name, 'update') AS update,
   HAS_TABLE_PRIVILEGE('analyst', table_name, 'delete') AS delete, 
   HAS_TABLE_PRIVILEGE('analyst', table_name, 'references') AS references 
FROM cte
ORDER BY table_name ASC;
