> Take the following SQL:
> SELECT CAST('11111111111111111111111111111111.111111' AS DECIMAL(38,6)) AS "num"
> And, in the default Calcite SQL dialect with all defaults, send it through Planner parse -> valiate -> rel to get a RelNode. The RelNode will have a Project with the "111111111111111.11111" literal in there as a RexLiteral with Decimal type. 
>  
> The use RelToSqlConverter to convert that RelNode back to SQL. The SQL now looks like 
> SELECT 11111111111111111111111111111111.111111 AS "num"
>  
> If you attempt to parse and validate that SQL, you get "Numeric literal '11111111111111111111111111111111.111111' out of range" throw by SqlValidatorImpl.validateLiteral()
