Review comment:
@srowen @dongjoon-hyun Does this behavior need to be consistent with
Java 8?
```
https://github.com/apache/spark/blob/128168d8c4019a1e10a9f1be734868524f6a09f0/sql/core/src/test/resources/sql-tests/inputs/postgreSQL/text.sql#L90-L91
```
It seems that Java 17 is same as PostgreSQL, but Java 8 returns the a non
ERROR result
```
