We should refer to the fact that jsonb is internally typed. This isn't
all that obvious now, but it is evident for example when you sort a
set of raw scalar numeric jsonb values, which has a sane ordering (the
implementation invokes numeric_cmp()). You also get an internal,
per-number-scalar display scale, just like the numeric type proper.
I'm not all that sure about how to go about succinctly expressing
this, but clearly it's important.
