[hibernate-issues] [Hibernate-JIRA] Closed: (HHH-1003) PostgreSQL dialect uses sequence instead of identity for id="native"

PostgreSQL dialect uses sequence instead of identity for id="native" -------------------------------------------------------------------- Key: HHH-1003 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1003 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.0.5 Environment: Hibernate 3.0.5 PostgreSQL 8.0.3 Reporter: Simone Bordet The class org.hibernate.dialect.PostgreSQLDialect overrides (incorrectly, I think, for PostgreSQL 8 at least) the method getNativeIdentifierGeneratorClass(), returning SequenceGenerator.class. Since PostgreSQL supports IdentityGenerator, via serial and bigserial data types, it would be cool to have it supported out of the box from Hibernate. Note that the behavior of the base class org.hibernate.dialect.Dialect is already what is needed; that is, there is no need to override getNativeIdentifierGeneratorClass() in PostgreSQLDialect. I have no idea if this is done for compatibility with older PostgreSQL versions; if so, maybe a solution like OracleDialect/Oracle9Dialect may be used. Thanks !
