We use Clickhouse version 22.3.3.44, and met with with some wrong behaviour - 
queries "ALTER TABLE ... MODIFY COMMENT ... " does not work on ReplicatedMergeTree engine.

Bug reproduce script:
```
CREATE TABLE sandbox.test__calendar
(
    `dttm` DateTime COMMENT 'date and time',
    `timestamp` Int64 COMMENT 'event timestamp',
    `year_num` Int32 COMMENT 'year number'
)
ENGINE = ReplicatedMergeTree() PARTITION BY year_num ORDER BY timestamp
COMMENT 'Comment text for test table';

SELECT comment FROM system.tables WHERE name like 'test__calendar'; -- 1 row selected with correct comment text

ALTER TABLE sandbox.test__calendar MODIFY COMMENT 'Some new more detailed text of comment';

SELECT comment FROM system.tables WHERE name like 'test__calendar'; -- 1 row selected, but with OLD(!) comment text
```

Maybe it will be helpfull, ALTER TABLE query returns such result:
```
host            |status|error|num_hosts_remaining|num_hosts_active|
----------------+------+----+-----------------------+------------------+
10.7.179.41     |     0|    |                      1|                 0|

```
}

    catch (const Coordination::Exception & e)

        if (parts_should_be_retried && Coordination::isHardwareError(e.code))
            parts_should_be_retried->insert(part_names.begin(), part_names.end());
        throw;
