Dandandan opened a new issue, #22232:
URL: https://github.com/apache/datafusion/issues/22232
### Describe the bug
Optimizer interval analysis panics when a `BETWEEN` predicate spans the
full `i64` range. `Interval::cardinality` finishes with
`.map(|result| result + 1)` and the `+ 1` overflows when the inner range
already equals `u64::MAX`.
### To Reproduce
```sql
SELECT * FROM (VALUES (1)) AS t(x)
WHERE x BETWEEN -9223372036854775808 AND 9223372036854775807;
```
### Actual behavior
```text
thread 'main' panicked at
datafusion/expr-common/src/interval_arithmetic.rs:968:23:
attempt to add with overflow
```
Call path: `Interval::cardinality::{{closure}}` → `cardinality_ratio`
→ `calculate_selectivity` → `shrink_boundaries` → `analyze`.
### Expected behavior
Cardinality should saturate (e.g. `u64::MAX`) or return `None`, not panic.
### Notes
Source:
https://github.com/apache/datafusion/blob/53.1.0/datafusion/expr-common/src/interval_arithmetic.rs#L968
Related but distinct from closed #16736 (float subtract overflow in the
same module).
Found via LLM-guided fuzz testing on DataFusion 53.1.0.
