What you want to do is to get into postgres and drop that table.

In broad strokes, it’s something like

```plaintext
./launcher enter app 
sudo postgres
psql 
drop table the_table _mentioned above ;

```

And then you should be able to run the upgrade.

Edit: but hopefully you make a database-only backup first just in case!
