Hello,

I am very new to Hibernate so my question might be stupid but I don't understand the @Id(generate=GeneratorType.AUTO) usage when using PostgreSQL. I thought that schema generation should generate autoincrement feature (sequence) in my PostgreSQL database for the id in the table but nothing such happens. Autoincrement sequence is created only when using GeneratorType.IDENTITY.

What should I do to get the autoincrement feature created for my id field in table using GeneratorType.AUTO and PostgreSQL? I would like to use GeneratorType.AUTO because Hibernate documentation states that it is "the preferred type for portable applications".

I use:
hibernate-3.1rc2
hibernate-annotations-3.1beta6
hibernate-entitymanager-3.1beta4

Thanks for any suggestion.

the primary generator for postgres is Sequence not identity.
If you want to change that, update the postgres dialect getNativeIdentifierGeneratorClass()
