Unable to upgrade trac after plugin Install

Reported by:… Owned by: jeangui
Priority: normal Component: DefaultCcPlugin

I am able to successfully install the defaultcc plugin into my trac environment using easy_install, however, I get the following error after attempting to upgrade my trac environment:

Traceback (most recent call last):

Resolution: fixed
Status: newclosed

I fixed this myself. Trac is unable to perform a backup of a PostGreSQL db so I had to do this manually.. and then perform the trac upgrade without the backup option:

trac-admin /path/to/projenv upgrade --no-backup

After I did these steps.. the plugin seems to work fine now.
