Erro ao utlizar JPA

Olá pessoal, estou fazendo uma aplicação simples utilizando JPA para saber se eu estou sabendo utilizar o mesmo. Mas, está dando erro. Segue abaixo o erro que aparece, as minhas duas classes, e o código sql para criar o BD e a tabela.
Utilizo o PostgreSQL 8.4 como BD, e adicionei a biblioteca do PostgreSQL, os jar…

Erro:
