[support] I have a new version of drupal 6.22 on another box which is ready for installation. Can I just point this new version of drupal to this newly restored postgres database and if so how would I do this?

I have an existing drupal 6.20 database backed up and restored to another postgres database. I also have a new version of drupal 6.22 on another box which is ready for installation. Can I just point this new version of drupal to this newly restored postgres database and if so how would I do this? Thanks, John
