I don't see any statement that claims the table or column names should be returned in upper case.
The driver should always return the names as _stored in the database_ which could mean lowercase, uppercase or mixed
casedepending on the DBMS. To find out _how_ the DBMS stores them you can use storesLowerCaseIdentifiers(),
storesMixedCaseIdentifiers()and storesUpperCaseIdentifiers()

Yes, because Postgres stores all (unquoted) identifiers in lowercase.
