rake db:seed not working in dev - pg is running but the connection is being refused

Question

I'm trying to follow along on this tutorial and can't get past the setup of pg. https://shellycloud.com/blog/2013/10/adding-search-and-autocomplete-to-a-rails-app-with-elasticsearch

I set up pg on my computer using the postgres app, and I installed it successfully in my app using bundle install, but whenever I run rake db:seed I get the error below. pg is running on port 5432, I've tried uninstalling and installing again. rails server runs fine, and psql is working in the terminal.

I have been searching for hours and can't find anything that can explain what the issue is - most answers are to do with sunspot solr which I'm not using. I have already increased my system's shared memory as advised in the postgres app documentation:

sudo sysctl -w kern.sysv.shmall=65536
sudo sysctl -w kern.sysv.shmmax=16777216

I added the following to my development config as another answer mentioned this as a potential solution:

config.action_mailer.perform_deliveries = false

Any help would be very much appreciated!

This is the error I get when I run rake db:seed

michaels-air:bookstore_search michaeltaylor$ rake db:seed --trace
