> The SQL-CLI now outputs the column name as the name that comes from the plan, which is  not that readable sometimes, i can think of 2 cases that can be promoted:
> * Expression like "a + b" should output "a + b" (i.e. the MySQL CLI) instead of "$Expr{index}"
> * We should always output the alias if it's there, now, the alias in the plan may be dropped because of 2 reasons:
>     1. Project remove rule would remove the project without considering the alias
>     2. after CALCITE-3713, some CALC/PROJ would be reused while ignoring the column alias
