crepererum opened a new issue, #6677: URL: https://github.com/apache/arrow-datafusion/issues/6677
### Describe the bug The `Debug` impl for `Expr` is a human-readable "nice" output: https://github.com/apache/arrow-datafusion/blob/6872535358c2c6b70350484e6cc7c058c7a806ae/datafusion/expr/src/expr.rs#L872-L883 However it should be as detailed as possible. E.g. there's no way to tell from that output if `f(x)` is a function call or a column named `f(x)` which some of the optimizer passes do. This makes leads to an extremely frustrating debugging experience, esp. when some pass or step complains that a certain column wasn't found. ### To Reproduce _No response_ ### Expected behavior Just auto-derive `Debug`. ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
