DDtKey opened a new issue, #6436: URL: https://github.com/apache/arrow-datafusion/issues/6436
### Describe the bug For versions `24` & `25` DF returns `Invalid function 'LENGTH'` when `enable_ident_normalization` is disabled. It was working with `22`. For example, it fails for upper-case functions names, like `LENGTH`, `CONCAT` and etc. I don't think normalization should affect it, because the name of functions should be case insensitive ### To Reproduce Set `enable_ident_normalization: false` and use select with any scalar-function in upper-case, like `select LENGTH(x) from my table` ### Expected behavior Name of functions should be case insensitive, normalization is separate step. ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
