Looking at the code now, I think there's at least one bad outcome of
this change: the behavior of CharGetDatum() is now ill-defined, because
we'll (probably) get different results on signed-char and unsigned-char
compilers. I think we'd be well advised to make that macro be
#define CharGetDatum(X) ((Datum) ((unsigned char) (X)))
