如何查看所有角色/user/group_role在postgres数据库中有哪些权限？

SELECT grantee,
       table_catalog,
       table_schema,
       table_name,
       privilege_type
FROM information_schema.role_table_grants
WHERE grantee IN (SELECT rolname FROM pg_roles)
ORDER BY table_schema, table_name;

SELECT grantee,
       privilege_type,
       object_type,
       object_name
FROM information_schema.role_usage_grants
WHERE grantee IN (SELECT rolname FROM pg_roles)
ORDER BY object_type, object_name;
