Now my question is if it makes sense, concerning performance, to store these integer values in arrays or if it is better to change the design so that the values are stored separately in fields in tables. I have to add, that it is not unlikely (or at least it won't happen very often) that select queries will try to find one of those specific values, but rather something like select * from persons where person_id=...

If the data isn't actually a vector, than it is probably better to not use
arrays. This will provide you with more flexibility.
