This is a very important feature. 🪜 Moving `TypeCoercion` into pre-optimizer phase would allow to avoid "Mismatch between schema and batches", like #5733 (and possibly #5695). `TypeCoercion` being **an optimizer** is a broken concept - because optimizers cannot change the final schema of the logical plan. What is more, `Expr::Case` has an assumption, that all inputs are **already** coerced. -- This is an automated message from the Apache Git Service.
