Hey, I set up the default discourse on a linux machine using this [guide](https://github.com/discourse/discourse/blob/master/docs/INSTALL-cloud.md). It went super smoothly, and the site came up perfectly.

I decided to allow users to connect via facebook, so I went through the facebook instructions linked to from the above link (I’d link again but new users can only post 2 links apparently). That ended up not working, but the site was still up and running (I don’t remember the error I got when trying to log in via facebook).

While going through the facebook docs I saw something about needing to have https enabled, so I started going through [these docs.](https://meta.discourse.org/t/setting-up-https-support-with-lets-encrypt/40709). That all went well until the `./launcher rebuild app`, where I got a postgres error. Which surprised me, because I hadn’t done anything to the postgres config (to the best of my knowledge). The first error is below:

```
INFO -- : > cd /var/www/discourse && su discourse -c 'bundle exec rake db:migrate'
rake aborted!
PG::ConnectionBad: could not connect to server: No such file or directory
	Is the server running locally and accepting
	connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

```

I didn’t stop the postgres service, but I tried running `service start postgres` and it said it wasn’t installed. So I assume it’s installed automatically some other way than I’m used to. Any ideas on what I could have done wrong? Thanks
