-------------------------------------
[~julianhyde] Hello, I have a confusion here. The second parameter n in
ADD_MONTHS(d, n) supports string, double and other types, but calcite does not
support date function calculations.
In my understanding, this should not be in line with the SQL standard. Should
we support it? I think if we support it, it may be a disaster.
