You can't return NEW in an ON DELETE trigger - there is no NEW record.
Since you're going with a STATEMENT trigger instead, that's not really
relevant anymore (no NEW _or_ OLD record, since statements aren't
necessarily involved with single records), but I thought I'd mention
that slight oversight ;)
