Review comment:
I think we needn't.
After Cluster readFields, we will construct a new InfoSchemaDb and add it
to Cluster immediately.
```
public long loadCluster(DataInputStream dis, long checksum) throws
IOException, DdlException {
if (Catalog.getCurrentCatalogJournalVersion() >=
FeMetaVersion.VERSION_30) {
int clusterCount = dis.readInt();
checksum ^= clusterCount;
for (long i = 0; i < clusterCount; ++i) {
final Cluster cluster = Cluster.read(dis);
...
final InfoSchemaDb db = new InfoSchemaDb(cluster.getName());
...
cluster.addDb(db.getFullName(), db.getId());
```
