erratic-pattern opened a new issue, #19069:
URL: https://github.com/apache/datafusion/issues/19069

   ### Describe the bug
   
   When logical and physical schema metadata mismatch, the error message does 
not show the metadata differences.
   
   Example:
   ```
   Error while planning query: Internal error: Physical input schema should be 
the same as the one converted from logical input schema. Differences: .
   ```
   
   The `Differences: .` is confusing because it does not show any differences.
   
   ### To Reproduce
   
   Execute a query on a parquet file with metadata and skip_metadata = false 
where the physical/logical metadata do not match.

   ### Expected behavior
   
   Error message should show metadata differences.
   
   ### Additional context
