Hi,
I use Hibernate 3.3.1 GA. Primary key in my class is of type string and generator is set to native. When I use HSQL db it generates table as:

create table BLAHBLAH (ID_ varchar(255) generated by default as identity (start with 1), primary key (ID_))

which of course raises error.

In PostgreSQL or H2 it generated ok:
create table BLAHBLAH (ID_ varchar(255) not null, primary key (ID_))

Is this a bug in Hibernate?
Is there any built-in generator which generates strings?

Thanks
