How to change a site setting via the Console

Support

So I did these commands:

cd /var/discourse
./launcher enter app

then
bundle exec rails c

and I’ve got the following errors:

URGENT: FATAL: Peer authentication failed for user “discourse”
Failed to initialize site default
/var/www/discourse/vendor/bundle/ruby/2.3.0/gems/activerecord-4.2.7.1/lib/active_record/connection_adapters/postgresql_adapter.rb:651:in initialize': FATAL: Peer authentication failed for user "discourse" (PG::ConnectionBad) from /var/www/discourse/vendor/bundle/ruby/2.3.0/gems/activerecord-4.2.7.1/lib/active_record/connection_adapters/postgresql_adapter.rb:651:in new’

I did ./launcher rebuild app and tried again. The same errors!

After I’d pissed of these problems. I did restored my droplet from a previous snapshot I had and started from scratch.

I did enabled FORCE_HTTPS without a problem.
