sorry about the confusion - I wasn't as involved in this process as I should have been. My fault. This is now fixed:
https://github.com/orioledb/orioledb/pull/558
The code is now Apache 2.0 which grants patent rights and can be re-licensed to PostgreSQL when the code is upstreamed. I'll amend the blog to make that clearer
Thanks for the fix!
From the phrasing it already seemed your heart was in the right place, but I understand that it can get tricky once people get involved who aren't as familiar with the details of open source licensing.
Getting legal to sign off on a different license this quickly is impressive!
