The problem above is with jBPM 5.4 . I also tried with jBPM 5.3 and with this 
version I can connect to PostgreSQL database, starting jBoss creates the 
schema. But then I have the following error in the jbpm-console :

With jBPM 5.4, the error was when starting jBoss : 
> 08:19:31,030 ERROR [org.hibernate.tool.hbm2ddl.SchemaUpdate] (MSC service 
> thread 1-1) HHH000388: Unsuccessful: create table Attachment (id bigint 
> generated by default as identity, accessType integer, attachedAt timestamp, 
> attachmentContentId bigint not null, contentType varchar(255), name 
> varchar(255), attachment_size integer, attachedBy_id varchar(255), 
> TaskData_Attachments_Id bigint, primary key (id))
> 08:19:31,046 ERROR [org.hibernate.tool.hbm2ddl.SchemaUpdate] (MSC service 
> thread 1-1) ERREUR: erreur de syntaxe sur ou près de « generated »

and this is why I tried to create the schema with a sql script.



I will try a new installation from scratch with jBPM 5.4, and if it still 
doesn't work I will try MySQL.
