Chef error: CREATE USER gitlab_mattermost

Looks like some form of permission issue, as it can’t seem to find access to the postgres instance. Any suggestions here are very welcome. I get this when running sudo gitlab-ctl reconfigure, and I have done the step of setting up the
mattermost_external_url correctly, AFAIK.

Hi @scottcorscadden, this may be an issue with GitLab 7.14.1, propose following this thread in GitLab omnibus:

Thanks very much @it33 - that was very helpful. Got what I needed over there.
