   When doing this job,I found that this function is quite similar with `collect_set`, except for the 'max_size ' limit.The sibling function `group_array` seems also in this situation.Shall we upgrade the `collect_set` and `collect_list`  to support the same semantics of the above two,or just simply create new functions as `group_uniq_array`  and  `group_array` ?
