That looks better! Will try to implement it soon.

I encountered a problem for `type_coercion` and need help🥲 Here `TypeCoercion` would rewrite an `Expr` thus brings a 'Cast', and the name for `Cast` would not just be the expr...

I encountered an issue: the plan's schema would change during rewrite stage.👀 In > explain verbose SELECT CAST(2 AS INTEGER); ``` +----------------------------------------------------------------------------+--------------------------------------------------------------------------------------+ | plan_type | plan | +----------------------------------------------------------------------------+--------------------------------------------------------------------------------------+ | initial_logical_plan...
