> The AND/OR boolean kernels currently have the same null handling as other
> binary expressions, if either the left or right input is NULL then the result
> will be NULL. The standard sql behaviour is different:
> OR: If one input is TRUE then the result will be TRUE even if the other input
> is NULL
> AND: If one input is FALSE then the result will be FALSE regardless of the
> other input
> This behaviour makes sense if you think of NULL as meaning UNKNOWN.
