Since they're bools, the C spec requires them to promote to integer
0 or 1, therefore the & operator will yield the desired result.
So there's not going to be any incorrect behavior.  Nonetheless,
I agree that && would be better, because it would short-circuit
the evaluation of parallel_vacuum_index_is_parallel_safe() when
there's no need.
