If you want one row per door_id whose set of available_id is exactly the same as the given array, you can use aggregation like so:

select door_id
from mytable
group by door_id
having array_agg(available_id order by available_id) = array[1,2,3,4,6,52]

If you are fine with subset containment:

having array_agg(available_id order by available_id) @> array[1,2,3,4,6,52]

If you want all corresponding rows, use window aggregation:

select *
from (
    select t.*, 
        array_agg(available_id order by available_id) over(partition by door_id) arr
    from mytable t
) t
where arr @> array[1,2,3,4,6,52]
