Yeah, I was just thinking about that. The core problem though is that
we need the "bool" fields in the system catalog structs (or anyplace
else that it represents an on-disk bool datum) to be understood as
being 1 byte wide. I do not think we can assume that that's true of
every compiler's _Bool type. So we'd need some workaround for that.
There are probably other places such as isnull arrays where it'd be
wise to force the width to be 1 byte.
In any case, that's a research project that's not getting done for v10.
