Oops. @hvanhovell . I found the original reason.
The logic of `isTemporaryTable` only lookup `current database`. We should
support the following.
```
val m3 = intercept[AnalysisException] {
catalog.getTableMetadata(TableIdentifier("view1", Some("default")))
}.getMessage
assert(m3.contains("Table or view 'view1' not found in database
'default'"))
```
