Alfresco Community Upgrade

[henrydl]

I'm trying to upgrade Alfresco2.1 Community to Alfresco3.0 Community (with Postgres Database)
First of all i don't find the scripts for the Postgres Upgrade (org.hibernate.dialect.PostgreSQLDialect) in

tomcat/webapps/alfresco/WEB-INF/classes/alfresco/dbscripts/upgrade/2.2/

So i have copied them from a Alfresco 3.2 installation.

Then i have:
- Installed Alfresco3.0 , launched and stopped to test if works
- Stopped Alfresco2.1
- Backed up Alfresco2.1 database with pg_dump
- Deleted all data in Alfresco3.0/alf_data directory
- Deleted Alfresco3.0 database
- Recreated Alfresco3.0 database and restored Alfresco2.1 backup
- Copied Alfresco2.1/alf_data/contentstore in Alfresco3.0/alf_data
- Launched Alfresco3.0
- All updates seems succesful, index are recreated, but finally i have this error:

Could you help me?
Thanks in advance

Are you using AVM?   If not then there's no need to run that patch.
