As you see the error is reported to occur on line 15 (inside MyDBI::db::selectrow_array), but I want it to be reported on line 38 (where selectrow_array is called).
Adapting DBI.pm's discussion of error handling, you might try: 
use Carp;

DBI->connect(...,
   { RootClass => ...,
     HandleError => sub {
        local $Carp::CarpLevel = 1;
        $_[0] = Carp::shortmess($_[0]);
        0;
     },
   }

Your subclass' connected method might install something like this by default, taking care to remember and summon a user-supplied HandleError, too.
