> In relational DB such as Postgres, this query works fine.
> "select ... from ... where column (INT type) between '10' and '11'"
> Calcite blocks this query early by the fact that data types "char" & "integer" are not directly compatible. However, this is very common for people to filter columns with date types. For example,
> "...where date between '1911-01-01' and '1911-01-02' "
> To relax this type check when comparing with literals can help improve usability.
