Thanks a lot. I'm going to implement your modifications this week or 
maybe next week.

Could you send me the translated .sql files for PostGres? I want to test 
  the installation process.

What do you want to check into the CDash repository? I think the best is 
probably to upload on the Wiki and put a description.
