[Dbix-class] overlaps

Any suggestions on how to use the overlaps operator? Using Postgresql..

I read the SQL::Abstract page after bottoming out on:
	Cannot mix placeholder styles ":foo" and "?"

I found this in the docs:

    my %where  = (
        user   => 'nwiger',
        completion_date => {
           -not_between => ['2002-10-01', '2003-02-06']
        }
    );

    Would give you:

    WHERE user = ? AND completion_date NOT BETWEEN ( ? AND ? )


But it doesn't seem to recognize OVERLAPS the same way as BETWEEN:

    (start_time,end_time)" => { -overlaps => [$pg_alpha, $pg_omega] }

generates:

    WHERE ( ( ( (start_time,end_time) OVERLAPS $1 ) OR ( ...

Of course what I want is 
    WHERE ( ( ( ( start_time,end_time) OVERLAPS (?, ?)

I could simulate overlaps with some OR clauses, but I made a mistake with that 
before, so I'd rather use the proper SQL function.
