[I] panic: date_trunc unwraps out-of-range lower-bound timestamp truncation [datafusion]
Dandandan opened a new issue, #22214:
URL: https://github.com/apache/datafusion/issues/22214
### Describe the bug
`date_trunc` can panic during planning/constant folding for lower-bound
nanosecond timestamps. Truncating to a coarser unit can produce a value outside
Arrow's nanosecond timestamp range, and the code unwraps `None`.
### To Reproduce
```sql
EXPLAIN SELECT date_trunc('year', TIMESTAMP '1677-09-22 00:00:00');
```
### Actual behavior
```text
thread 'main' panicked at
datafusion/functions/src/datetime/date_trunc.rs:649:14:
called `Option::unwrap()` on a `None` value
```
### Expected behavior
Return an error or NULL for an out-of-range truncated timestamp; do not
panic.
### Notes
Other coarse granularities near the lower nanosecond timestamp bound hit the
same unwrap.
