[~jacobroldan], yeah, you are right, 1.21 supports implicit type coercion for
DATE and TIMESTAMP in binary comparison, i think we can support between either.
For current coercion rules, for "date > timestamp", we coerce the DATE to
TIMESTAMP.
[~julianhyde] I have checked MYSQL 5.6 and PostgreSQL 9.6, they have the same
behavior with Calcite.

Not a bug. I think it is a yet implemented feature.

Since calcite 1.21 it's possible to do
{code:sql}
date '1999-03-02' < timestamp '1999-03-03 00:00:00.0'
{code}
but not with {{_between_}}
I don't know if it's a feature (I haven't seen anything in the release note) or
if it's a bug

If we do this, we should also allow other comparisons, e.g. {{aDate <
aTimestamp}}.
Note that we already allow {{aDate < aString}}, and the string is implicitly
converted to a data. This feature should work the same way: the date should be
converted to a timestamp, or the timestamp to a date. Which should it be? What
do other databases do?
