Review comment:
Can you just remove this entire block? This will allow for a single
return statement at the bottom and also allows the cleanup to happen.

Review comment:
Same here....
```java
List<Object[]> list = Batchable.runBatched(batchSize, colNames, b);
final ColumnStatistics result;
if (list.isEmpty()) {
result = null;
} else {
ColumnStatisticsDesc csd = new ColumnStatisticsDesc(true, dbName,
tableName);
csd.setCatName(catName);
result = makeColumnStats(list, csd, 0, engine);
}
b.closeAllQueries();
return result;
}
