Blob is null with Postgresql
----------------------------

                 Key: ANN-677
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-677
             Project: Hibernate Annotations
          Issue Type: Bug
    Affects Versions: 3.2.1
         Environment: hibernate-3.2.1, hibernate-annotations-3.2.1, postgresql-8.2.5-1.fc7, postgresql-jdbc-8.2.504-1jpp.fc7 and postgresql-8.2-506.jdbc4.jar
            Reporter: Aaron Luchko
         Attachments: hibPostgresbug.zip

I've found that after a sequence of queries, starting new transactions and clearing the session, a Blob will not be successfully from the database and null will be returned by the InputStream instead. Using the debugger I've followed this into the jdbc code and from what I can tell some message is sent to load the blob but the database replies with an empty set of data which naturally causes the InputStream to read null.

I've attached a test case (sorry, no makefile or pom.xml, I just ran it using eclipse) which, for me, replicates the bug.

Note I've also used hsqldb and mysql and didn't see the bug with them, only postgresql.

thanks,
Aaron
