I am trying to update all my users profiles to turn off mailing list mode, however, I get an error when issuing the rails command:

```
./launcher enter app
rails c
User.update_all(mailing_list_mode: false)

```

The error is:

```
ActiveRecord::StatementInvalid: PG::UndefinedColumn: ERROR: column "mailing_list_mode" of relation "users" does not exist
LINE 1: UPDATE "users" SET "mailing_list_mode" = 'f'
                       ^
: UPDATE "users" SET "mailing_list_mode" = 'f'
from /var/www/discourse/vendor/bundle/ruby/2.3.0/gems/rack-mini-profiler-0.10.1/lib/patches/db/pg.rb:90:in `exec'

```
