Hibernate saving User model to Postgres

You need to escape the table name when using reserved keywords. In JPA 1.0, there is no standardized way and the Hibernate specific solution is to use backticks:

@Entity
@Table(name="`User`")
public class User {
    ...
}

In JPA 2.0, the standardized syntax looks like this:

@Entity
@Table(name="\"User\"")
public class User {
    ...
}
