I gave a 0777 permissions to /var (I didn't know back then that it's a really bad thing to do) I did this while in /var :

chmod -R 0777 *

after I did this postgresql fails to restart everytime. my question is, how can I return the whole /var permission tree to its default status ?

Restore from your latest backup. If you don't want to overwrite data, check your permissions on your backup media and write a shell script to set the permissions on your disk according to what you have on your backups. –  Jenny D Jun 18 '13 at 13:44

You should solve this issue by restoring your system from a backup that was taken before you did this.
