I tried doing a SKIP_POST_DEPLOYMENT_MIGRATIONS=false rake db:migrate to see if that would help, but no joy.

I checked the commits at Commits · discourse/discourse · GitHub and it looks like my server is more up to date.

I feel like I must be doing something stupid, but I can’t see what it could be

Probably just a migration from a plugin that isn’t installed on your system. Replacing the version number in the filename should solve it.

[pfaffman (Jay Pfaffman)]

Aha. I was wondering about plugins and whether I needed to install them all. And renaming the file is embarrassingly simple.

That worked, but I’ll rebuild with the plugins likely to be at play in case something needs to be there when I merge these two sites.

Thanks very much.
