SQL cannot add columns to query

Question

I have the following query (PostgreSQL 9.5.19):

with userlist as (
  select a.ips, 
         array_agg(t.super_user_id) as super_users
  from tmp_table_1 t
    left join unnest(t.ips) as a(ips) on true
  group by a.ips
), shared_users as (
  select u.ips,
         array(select distinct ul.uid
               from userlist u2, unnest(u2.super_users) as ul(uid)
               where u.super_users && u2.super_users
               order by ul.uid) as super_users
  from userlist u
)
select s.super_users, array_agg(distinct s.ips) as ips, 
    (select sum(msg_count) from tmp_table_1 where super_user_id in s.super_users) as sum_msg_count
from shared_users s
group by s.super_users;

I get the following error:

ERROR:  syntax error at or near "s"
LINE 38: ...sg_count) from tmp_table_1 where super_user_id in s.super_us...
                                                              ^

It seems like I cannot access s.super_users from within the subquery.

Anyone know how I can do this?

Maybe I am not approaching this correctly?

Question

How can I add the additional columns (sum_msg_count, sum_user_count, max_last_date and pubs) to the result set?

Desired result

|super_users                      |  ips                                                        |sum_msg_count| sum_user_count  |   max_last_date                | pubs                        |
|---------------------------------|-------------------------------------------------------------|-------------|-----------------|--------------------------------|-----------------------------|
|{522460771,522460772,522460773}  |  {94.134.88.115,94.134.88.124,94.134.88.125,94.134.88.136}  | 30          |         9       |  "2018-06-30 21:29:48.664000"  |  {ad2,googlecooler,ads,ad1} |

|{522460776}                      |  {8.8.8.8}                                                  | 10          |         3       |  "2018-06-30 21:29:48.664000"  |  {googlecooler,ads}         |

Answer 1

You should use ANY, not IN to search in an array

...where super_user_id = ANY (s.super_users)

Answer 2

with userlist as (
  select a.ips, array_agg(t.super_user_id) as super_users
  from tmp_table_1 t
    left join unnest(t.ips) as a(ips) on true
  group by a.ips
),
shared_users as (
  select u.ips,
         array(select distinct ul.uid
               from userlist u2, unnest(u2.super_users) as ul(uid)
               where u.super_users && u2.super_users
               order by ul.uid) as super_users
  from userlist u
) --select * from shared_users
select s.super_users, array_agg(distinct s.ips) as ips, 
(select sum(msg_count) from tmp_table_1 where super_user_id = any(s.super_users)) as sum_msg_count,
(select sum(user_count) from tmp_table_1 where super_user_id = any(s.super_users)) as sum_user_count,
(select max(last_date) from tmp_table_1 where super_user_id = any(s.super_users)) as max_last_date,
(select array_agg(pubs) from (select a.pubs, array_agg(t.super_user_id) as super_users
    from tmp_table_1 t 
  left join unnest(t.pubs) as a(pubs) on true
  and t.super_user_id = any(s.super_users)
  where a.pubs is not null
  group by a.pubs) as pubsAlias) as pubs  
from shared_users s
group by s.super_users;
