I checked this on current `main` (`e7e037d`).
The original planning error is gone. Date32/Date64 `+`/`-` integer is
treated as a number of days (Postgres-compatible), including the commutative
`integer + date` form:
```sql
SELECT to_date('1970-01-01') + 5;
-- 1970-01-06
SELECT '1970-01-01'::date + 5;
-- 1970-01-06
```
This was added in #19460 (`arith_date_integer.slt` and the
`temporal_math_coercion` Date+Int → Date+Interval path).
One caveat on the exact issue query: `to_date('1970-01-01', 'yyyy-mm-dd')`
still fails because DataFusion uses Chrono strftime patterns (`%Y-%m-%d`), not
Oracle/`yyyy-mm-dd`. That is independent of the Date32+Int64 coercion bug.
`to_date('1970-01-01') + 5` and `to_date('1970-01-01', '%Y-%m-%d') + 5` both
work.
I think this can be closed as fixed by #19460, as @Omega359 noted.
