### Is your feature request related to a problem or challenge? Users may need to combine tables with differing column orders or missing columns as evolving schemas. Currently, AFAIK we require columns to match by position, forcing manual schema adjustments. ### Describe the solution you'd like Implement a UNION ALL BY NAME operator or modify the existing one such that it: * matches columns by name rather than by position. * fills missing columns with NULLs. * optionally supports similar flexibility in INSERT operations (e.g., INSERT INTO ... BY NAME). ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
