Try declaring returnValue as typ_history_rec_format instead of RECORD.

Get rid of the record constructor:

select into returnValue workarea.interface, workarea.updatedTime,
work_rftype, workarea.rfspeed;

Using your code with the above two changes and some canned data, I
got the function to work (where "work" means it ran and returned
some rows -- I didn't look closely at the logic to see if the results
were actually correct ;-).
