void[] get_bytes(int n) { return sqlite3_column_blob(stmt, n); }

void[] has a length, so you have to know the length. Assuming the length 
is n... Maybe try something like this (untested):

struct DynArray
{
    public void* ptr;
    public size_t length;
    public T[] toArray(T)() { return cast(T[]) cast(void*) (*this); }
}

void[] get_bytes(int n)
{
    return DynArray(sqlite3_column_blob(stmt, n), n).toArray!(void);
}
