Review Comment:
Append the following in timestamp_ns.q and run once.
```
CREATE TABLE t_nano_source (
id int,
ts_ns nanosecond timestamp
) STORED BY ICEBERG TBLPROPERTIES ('format-version'='3');
INSERT INTO t_nano_source VALUES (1, '2025-12-24 10:00:00.123456789');
select * from t_nano_source;
CREATE TABLE t_nano_target STORED BY ICEBERG AS SELECT * FROM t_nano_source;
select * from t_nano_target;
DESCRIBE t_nano_target;
```
The CTAS table (t_nano_target) is having column as `timestamp`:
```
POSTHOOK: query: select * from t_nano_target
POSTHOOK: type: QUERY
POSTHOOK: Input: default@t_nano_target
POSTHOOK: Output: hdfs://### HDFS PATH ###
