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?
