I've just upgraded to 5.2.15, I come from 5.1.0.

I have only one entity with only one field having annotated with @lob.

I'm not anymore able to get those entities due to this:

javax.persistence.PersistenceException: org.hibernate.HibernateException: Unable to access lob stream
...
Caused by: org.hibernate.HibernateException: Unable to access lob stream
...
Caused by: org.postgresql.util.PSQLException: Non è possibile impostare i «Large Object» in modalità «auto-commit».

I've read this but for what I understand using 5.2.15 with @lob should change nothing compared with releases prior to 5.2.9, am I wrong?
