logging issue - Mailing list pgsql-admin

PostgreSQL 9.1.3

I just moved our test database from PostgreSQL 9.0 to 9.1.  I also changed my log settings.   I am seeing every single SQL statement that PostgreSQL performs by my Java applications.  Is there some way to only display the details when there is an error?  I would assume yes.  But for some reason I am getting all SQL statements.  I just want the errors.  I have included below my settings for the logging section.  Any help would be greatly appreciated.  Thanks!
