It doesn't seem very helpful. AFAICS, we should interpret storing
'23:59:59.99' into a TIME(0) field as a cast from TIME(2) to TIME(0),
and the spec defines that as
15) If TD is the datetime data type TIME WITHOUT TIME ZONE, then let
TSP be the <time precision> of TD.
b) If SD is TIME WITHOUT TIME ZONE, then TV is SV, with
implementation-defined rounding or truncation if necessary.
So it's "implementation-defined" what we do.
