PG::ConnectionBad: fe_sendauth: no password supplied

Question

When I attempt to run \"rake test\" on a local postgres database, it throws the above exception.

Here is my pg_hba.conf file: # Database administrative login by

Answer 1

I use Postgres App. Which is really great because you don't have to supply username and password in the default part of the database.yml

database.yml

default: &default
  adapter: postgresql
  encoding: unicode
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>

development:
  <<: *default
  database: my-app_development

test:
  <<: *default
  database: my-app_test

production:
  <<: *default
  database: my-app_production
  username: my-app
  password: <%= ENV['MY-APP_DATABASE_PASSWORD'] %>

My problem: I changed the path and wasn't able to get postgres to work.

Solution: use the documentation to:

1) Uninstall the app

2) Stop the postgres process using this answer, which says to use sudo pkill -u postgres

3) Reinstall and start the app

Everything should work fine now, have a great day!

Note: Doing this also solves the problem Postgres.app port 5432 in use
