> In my Calcite code, I have a RexLiteral that is of type RelDataType.VARCHAR
> (the SqlTypeName is always CHAR)
> However, this information is getting lost in the call here
> [https://github.com/apache/calcite/blob/main/core/src/main/java/org/apache/calcite/rex/RexSimplify.java#L527]
> The result of this simplification gives me a RelDataType.CHAR instead.
