Second fix for returning with multiple entries in DB IO

- all data stored in array (size contrain needs to be checked)
- allows any returning data
- only named rows are returned (no numbers for column access)
- if multiple rows then insert_id is an array with the return data
- if single row the insert_id holds the PK, and insert_id_ext holds
extended data if exists
