Upgrade from 4.6 to 4.72 DB error - no such field
I just did an Upgrade from Civicrm 4.6.11 to 4.7.2 - (plan copy) which went without any error - so please try the below and update the result 

Just TEST This First 
I guess you had Payment processor enabled in your previous version and which has extra column for the payment processor type

So please try to Roll back to your previous version of CiviCRM 4.6 first 

Then try to delete the payment processor or Disable the payment processor and try to Upgrade to Civicrm 4.7.2

Also if possible try to disable all the extension too.
