prepared statements don't log arguments?

Hi!

When setting log_statement = all, and using JDBC PreparedStatements, I get
$n in the log where the real arguments used to be in previous versions of
postgresql:

postgres[30059]: [97-1] LOG: statement: INSERT INTO group_data
(this_group_id, item_text, link_path) VALUES ($1, $2, $3)

I really need to know the *real* arguments... How can I get them? Is it a
bug?
