URL: https://github.com/apache/datafusion/issues/11412
### Describe the bug
This query should be valid and can be executed on DuckDB, but produced an
Internal Error when building initial physical plan.
Full reproducer:
```
/*DML*/CREATE TABLE t60(v0 BIGINT, v1 BIGINT, v2 BOOLEAN, v3 BOOLEAN);
/*DML*/CREATE TABLE t0(v0 DOUBLE, v1 BIGINT);
/*DML*/CREATE TABLE t1(v0 DOUBLE);
SELECT COUNT(*)
FROM t1
NATURAL JOIN t60
INNER JOIN t0
ON t60.v1 = t0.v0
AND t0.v1 > t60.v1;
```
Error messages
```
> SELECT COUNT(*)
FROM t1
NATURAL JOIN t60
INNER JOIN t0
ON t60.v1 = t0.v0
AND t0.v1 > t60.v1;
Internal error: Invalid join key. Expected column, found Cast(Cast { expr:
Column(Column { relation: Some(Bare { table: "t60" }), name: "v0" }),
data_type: Float64 }).
This was likely caused by a bug in DataFusion's code and we would welcome
that you file an bug report in our issue tracker
