With pg_lfind8_nonzero(), we can write the code like this:

```
        if (likely(numberOfAttributes > 0))
                hasnull = pg_lfind8_nonzero((uint8 *) isnull, 
numberOfAttributes);
```

The pg_lfind8_nonzero() is faster because we can handle 8 bool values at a time.

Maybe you could try popcount for this?

    hasnull = (pg_popcount((char *) isnull, numberOfAttributes) > 0);
