This only checks for the null value.  I don't think we need to change
the function's name, but we do need to be more precise in the
documentation that it checks for the null value and not values that are
null.

Perhaps replacing "Produces an error if the input is null, and returns
the input otherwise." with "Produces an error if the input is the null
value, and returns the input otherwise."

Then also add ROW(NULL, NULL)) to the regressions tests showing that we
are aware that that is the behavior for things that are null but are not
the null value.
