ERROR: column ci_commits.gl_project_id does not exist

Hi all,

After updating to 8.1.2 (Omnibus) on Ubuntu 14.04, I get a HTTP 500 after logging in on my Gitlab instance. The Rails logs show this error:

A column seems to be missing in the DB, but gitlab-ctl upgrade and gitlab-ctl reconfigure show no errors. Am I missing something?

Thanks in advance!
