jayzhan211 opened a new issue, #12052:
URL: https://github.com/apache/datafusion/issues/12052
### Describe the bug
In #11907, interval that is less than a day is not supported
We could find out a way to support this query
`select generate_series('2021-01-01'::timestamp, '2021-01-02'::timestamp,
INTERVAL '1' HOUR);`
### To Reproduce
Result on `main`
```
query error DataFusion error: Execution error: Cannot generate date range
less than 1 day\.
select generate_series('2021-01-01'::timestamp, '2021-01-02'::timestamp,
INTERVAL '1' HOUR);
tamp, '2021-01-02'::timestamp, INTERVAL '1' HOUR);
```
### Expected behavior
Result from DuckDB
```
D select generate_series('2021-01-01'::timestamp, '2021-01-02'::timestamp,
INTERVAL '1' HOUR);
┌─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┐
│ generate_series(CAST('2021-01-01' AS TIMESTAMP), CAST('2021-01-02' AS
TIMESTAMP), to_hours(CAST(trunc(CAST('1' AS DOUBLE)) AS BIGINT))) │
