Hi
I'm using in my wokstation(Windows XP) PostgreSQL DB server and when I try code generation using hibernate tools(the latest version) the process failed. >The message that show me in the console is:

Full stack trace of any exception that occurs:

Name and version of the database you are using:
PostgreSQL 8.2 under Windows

If I use the Db server(version 8.2) in Ubuntu Linux(a server in my company) and the process is ok.
I prove with another DB Server in my workstation(MySQL and SQL Server) and the hibernate tools works very well.

The table has Primary key, and if I browse this using pgadmin (with the same account and password that I use to conenct using hibernate) this works perfectly.

My jdbc driver is: postgresql-8.2-505.jdbc3

I hope for your answer
