PostgreSQL的权限查询

查看哪些用户对表t1有哪些权限： part00=# \z t1 Access privileges Schema | Name | Type | Access privileges | Column access privileges --------+------+-------+---------------------+-------------------------- public | t1 | table | osdba=arwdDxt/osdba+| | | | scott=D/osdba |
part00=# \dp t1 Access privileges Schema | Name | Type | Access privileges | Column access privileges --------+------+-------+---------------------+-------------------------- public | t1 | table | osdba=arwdDxt/osdba+| | | | scott=D/osdba | (1 row) 可以看出有两个用户osdba和scott，osdba用arwdDxt权限，scott用户有D权限。字母代表的权限的意思如下： a: insert r: select w: update d: delete x: references t: trigger D: truncate
也可以查询系统视图pg_class part00=# select relname,relacl from pg_class where relname='t1'; relname | relacl ---------+------------------------------------- t1 | {osdba=arwdDxt/osdba,scott=D/osdba} (1 row)
如果想查询用户scott有哪些权限，可以查询系统表information_schema.role_table_grants: part00=# select * from INFORMATION_SCHEMA.role_table_grants where grantee='scott'; grantor | grantee | table_catalog | table_schema | table_name | privilege_type | is_grantable | with_hierarchy ---------+---------+---------------+--------------+------------+----------------+--------------+---------------- osdba | scott | part00 | public | t4 | SELECT | NO | NO osdba | scott | part00 | public | t1 | TRUNCATE | NO | NO
