You don't need select into here - the sample below deletes everything older 
than one day. You should be able to adapt it to your needs. Your example had 
a + rather than a - which would delete things in the future, that might have 
been what you intended, or it might not.

The RAISE NOTICE line prints a useful debug value. I like to scatter these 
around while I'm testing.

CREATE FUNCTION del_old_history() RETURNS int4 AS '
DECLARE
   var_history_age_limit int4;
   set_time    timestamp;
BEGIN
    var_history_age_limit:=1;
    set_time := current_date() - (var_history_age_limit::text || ''  days 
'')::interval;
    RAISE NOTICE ''set time = %'',set_time;
    delete from history where complete_time <= set_time;

    return var_history_age_limit;
END;'
LANGUAGE 'plpgsql';
