I have a multisite instance in which a bunch of databases failed to migrate because
```
PG::DuplicateColumn: ERROR: column "bookmarkable_id" of relation "bookmarks" already exists
```
maybe I should go delete that column from that table in those databases?
looks like it was because previous migrations hadn’t run due to SKIP\_POST\_DEPLOYMENT\_MIGRATIONS being set and previous migrations hadn’t finished.
I’ll delete this when I confirm that’s true…

@martin any ideas, may be related to the recent refactors?

Sorry for the false alarm. I so hate when I do this.
The issue was that I had `SKIP_POST_DEPLOYMENT_MIGRATIONS: 1` set and then didn’t run `multisite:migrate`. After I did a `SKIP\_POST\_DEPLOYMENT\_MIGRATIONS=- multisite:migrate’ I was then able to bootstrap.
I just need to fix my tooling for multisite to run the migration after cranking up the new semi-migrated container.

But strange. [Recovering from failed/partially applied upgrade](https://meta.discourse.org/t/recovering-from-failed-partially-applied-upgrade/221924) seems to have the same issue and it appears to be a [standard install](https://meta.discourse.org/t/142537?silent=true).

I would’ve replied to this post, but figured it was the same symptom of a different problem. 🙂 I admittedly don’t know enough to confirm either way…

Seems to be related to [DEV: Re-add polymorphic bookmark columns (#16261) · discourse/discourse@8040b95 · GitHub](https://github.com/discourse/discourse/commit/8040b95e8c4abeab1ab9fe50826f92c52995a814)

Wow. That seems to explain it.

Any update on this?
Mine is coming up with the same issue.
How would i copy this git into my discourse?
