The current driver returns this correctly for a ResultSet.

Here is a "transcript" from running my application on the console
(easier to copy & paste than a screenshot)

SQL Workbench/J console interface started.
Enter 'exit' to quit.
Enter 'WbHelp' for a list of SQL Workbench/J specific commands
Config directory: C:\Projects\sqlworkbench\conf

SQL> wbconnect {Postgres}/WbTest;
Connection to "User=thomas, Schema=public, URL=jdbc:postgresql://localhost/wbtest" successful

thomas(at)wbtest/public> create table foo ("ID" integer, "Bar" varchar, "FoBaR" varchar);
Table 'foo' created
thomas(at)wbtest/public> insert into foo values (1, 'foo', 'bar');
INSERT executed successfully
1 row affected
thomas(at)wbtest/public> select * from foo;
ID | Bar | FoBaR
---+-----+------
1 | foo | bar

(1 Row)
SELECT executed successfully
thomas(at)wbtest/public>

All the various API calls in DatabaseMetaData do return identifiers in the correct case as well.
