Hibernate com annotations

Olá pessoal!

Gostaria da ajuda de vocês.....

Estou com o seguinte problema:
Caused by: java.lang.AbstractMethodError: org.postgresql.jdbc2.Jdbc2DatabaseMetaData.supportsGetGeneratedKeys()Z

quando tento executar o meu programa que utiliza o hibernate.

Tenho os seguintes jars:
