Dandandan opened a new issue, #7700:
URL: https://github.com/apache/arrow-datafusion/issues/7700

   ### Describe the bug
   
   SimplifyExpressions doesn't have access to the entire schema, resulting in planning errors when the filter can be pushed down entirely to the tablescan.
   
   ```
           let fields = vec![
               Field::new("a", DataType::UInt32, false),
               Field::new("b", DataType::UInt32, false),
               Field::new("c", DataType::UInt32, false),
           ];
   
           let schema = Schema::new(fields);
   
           let table_scan = table_scan_with_filters(
               Some("test"),
               &schema,
               Some(vec![0]),
               vec![col("b").is_not_null()],
           )?
           .build()?;
           assert_eq!(1, table_scan.schema().fields().len());
           assert_fields_eq(&table_scan, vec!["a"]);
   
           let expected = "TableScan: test projection=[a], full_filters=[Boolean(true) AS b IS NOT NULL]";
   
           assert_optimized_plan_eq(&table_scan, expected)
   ```
