**Describe the unexpected behaviour**
max(date) and min(date) always return the same negative value: -127593672

**How to reproduce**
ClickHouse version: Docker -- clickhouse/clickhouse-server:22.6.8.35-alpine
Architecture: linux/arm64

```
MySQL [test]> create table test_date (
  date Int32,
  hour Int32
  ) ENGINE = MergeTree ORDER BY (date);
    ->     ->     -> Query OK, 0 rows affected (0.01 sec)
```
```
MySQL [test]> insert into test_date values(20220920, 1);
Query OK, 1 row affected (0.00 sec)
```
```
MySQL [test]> select max(date) from test_date;
+-----------------+
| maxOrNull(date) |
+-----------------+
| -127593672      |
+-----------------+
1 row in set (0.00 sec)
```
```
MySQL [test]> select max(hour) from test_date;
+-----------------+
| maxOrNull(hour) |
+-----------------+
| 1               |
+-----------------+
1 row in set (0.00 sec)
```
**Expected behavior**
I expect it to return ``20220920``.

    return max_block_num;
