Review comment:
I think it should be handled on the Schema validation level but not
while setting the PreparedStatement value.
I have just tested this case, and I have not been able to create Row with a
null value in the non-nullable field. It has failed with
```
java.lang.IllegalArgumentException: INT64 NOT NULL is not nullable in field
bigint_col
at
org.apache.beam.sdk.values.RowUtils$RowFieldMatcher.match(RowUtils.java:211)
```
