Thanks, that really helps!

Did you were tracking the `beta` branch at some point and then switched to `stable`? The `private_message` column was added in `v2.6.0.beta2`, but the commit is not included in `v2.5.2 +2`. This is the commit:

[https://github.com/discourse/discourse/commit/92b7fe4c62094275c5dd09b1f3dac5c5cbcad1c0](https://github.com/discourse/discourse/commit/92b7fe4c62094275c5dd09b1f3dac5c5cbcad1c0)
