Database upgrade fails on PostgreSQL

[hrvelic@…]

Hello. I have done the following: 1) Downloaded and unzipped the plugin from it's homepage on trac-hacks file name is: discussionplugin-r967.zip 2) I have built the egg using python setup.py bdist_egg and installed it with easy_install --always-unzip options. 3) I have added the following lines to the global trac.ini: [components] tracdiscussion.* = enabled

[discussion] title = Discussion

4) I have tried upgrading the environment with: trac-admin /path/to/env upgrade --no-backup Unfortunately, it ended up with an error: Command failed: ERROR: column "discussion_version" does not exist

INSERT INTO system VALUES ("discussion_version", 1);

I'm using the following:

• Ubuntu 6.06 Dapper Drake
• Apache 2.0.xx
• mod_python
• Python 2.4
• Trac 0.9.5
• PostgreSQL 8.1

Thanks, Hrvoje Velic
