Failover @Type for h2?
You could try to extend H2Dialect and bind varchar to type Type.otherpg-uuid is using Type.OTHER
public class H2PostgresDialect extends H2Dialect { public H2PostgresDialect() { super(); registerColumnType(Types.OTHER, "varchar(255)"); }}Remember to use register custom dialect class instead of standard one
But why just don't use
@Idprivate UUID id = UUID.randomUUID();
