我在postgres上有一个示例数据集

updated_at     activated_at        name     gender   role    school  app_name    device_type
-------------+-----------------+----------+--------+-------+---------+---------+---------------
August 2         July 30            Ron        M       S        A         Y          android
August 1         July 30            Ron        M       S        A         Z          browser
July 30          July 30            Ron        M       S        A         Y          android
August 1         July 28            Ana        F       S        B         Y          android
August 1         July 28            Ana        F       S        B         Z          browser
July 28          July 28            Ana        F       S        B         Y          android

我想知道什么时候是用户第一次显示（更新）后，它的激活时间和属于哪个应用程序。
预期结果：

updated_at     activated_at        name     gender   role    school  app_name    device_type
-------------+-----------------+----------+--------+-------+---------+---------+---------------
July 30          July 30            Ron        M       S        A         Y          android
July 28          July 28            Ana        F       S        B         Y          android

我尝试了以下sql：

SELECT min(ut.updated_at), u.activated_at, u.full_name, u.gender, r.name, s.name, ut.app_name, ut.device_type
FROM "public"."user_tokens" ut JOIN
     "public"."users" u
     ON ut.user_id = u.id JOIN
     "public"."user_roles" ur
     ON ut.user_id = ur.user_id JOIN
     "public"."roles" r
     ON ur.role_id = r.id JOIN
     "public"."schools" s
      ON ur.school_id = s.id
WHERE (NOT (ut.app_name) like 'G')
Group by u.activated_at, u.full_name, u.gender, r.name, s.name, ut.app_name, ut.device_type
Order by u.activated_at desc

但结果是这样的：

updated_at     activated_at        name     gender   role    school  app_name    device_type
-------------+-----------------+----------+--------+-------+---------+---------+---------------
August 1         July 30            Ron        M       S        A         Z          browser
July 30          July 30            Ron        M       S        A         Y          android
August 1         July 28            Ana        F       S        B         Z          browser
July 28          July 28            Ana        F       S        B         Y          android

我试图排除 app_name 以及 device_type 从GROUPBY子句 ERROR: column "ut.app_name" must appear in the GROUP BY clause or be used in an aggregate function 你知道怎么解决吗？任何意见都将不胜感激。谢谢您。
