QueryTest - PostgreSQL - "ERROR: operator does not exist: character varying = bytea"
------------------------------------------------------------------------------------

                 Key: EJB-404
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-404
             Project: Hibernate Entity Manager
          Issue Type: Patch
          Components: EntityManager
         Environment: PostgreSQL and Entity Manager 
            Reporter: Juraci Paixao Krohling
            Assignee: Juraci Paixao Krohling
         Attachments: QueryTest_2.diff

Test org.hibernate.ejb.test.QueryTest#testIsNull fails due to this query:
select i from Item i where (i.descr is null and :descr is null) or i.descr = :descr

When changing the query to what it reads below, it works properly:
select i from Item i where i.descr = :descr or (i.descr is null and :descr is null)

As this happened only with PostgreSQL, I assume this is an issue with either the driver or with the database itself. Will dig into pgsql's site to find out more about this issue.
