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)
```
