8.0 + JDBC3 Driver

First, I have an oddity with the 8.0-310.jdbc3 driver.  When I
query the db, I have to explicity specify the ResultSet type and
concurrency if I want something other than a FORWARD_ONLY
ResultSet.  This was not necessary in 7.4.  How do I tell when a
table will return a FORWARD_ONLY ResultSet by default?

Second, I'm having a problem with a query, which I will get to
in a second.  However, I notice from the stack trace that calls
are being made into the jdbc2 portion of the driver, even though
I am using the JDBC3 Jar with JDK 1.5.  Is this normal, or is there
something wrong?

Third, this is my actual problem:

INSERT INTO my_table
    (my_fields, ...)
    VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
    ;
SELECT currval('my_schema.my_seq')
    ;

I do a prepareStatement() with the above query, I fill in the params,
and I call executeQuery() hoping to get a ResultSet.  However,
instead I get:

PSQLException: No results were returned by the query.

But if I run the query in pgAdmin, it works just fine,
not to mention that this worked perfectly under 7.4,
and works just fine under 8.0 in another app.  Any
suggestions welcome.
