>Solution :

You can use array_agg aggregate function:

-- sample data
with dataset(id, interest) as(
    values (1,  'Math'),
        (1,  'Poetry'),
        (1,  'Art'),
        (2,  'Math'),
        (2,  'Other')
)

-- query
select id, array_agg(interest) interest
from dataset
group by id

Output:
