ruby on rails cannot connect to postgresql locally

I have been trying to set up my ruby on rails dev environment for a project I just started working on. I have installed Ruby 1.9.3, Rails 3.2, and postgresql 9.1.4 on Ubuntu 12, and when I try rake db:create:all I get the message:

/var/lib/gems/1.9.1/gems/activerecord-3.2.3/lib/active_record/connection_adapters/postgresql_adapter.rb:1194:in `initialize': could not connect to server: No such file or directory (NameError)
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

I then added:

host: localhost

port: 5432

to my database.yml file, which let me do db:create:all and db:migrate, but when I run the rails server locally it still has the same error.

I have checked that the postgresql server is running, which it is (I also know it is running since rake worked earlier), and have tried a fresh install of postgresql. What might I be missing to make this work?

Are you sure your postgres server is running? If you do ps -aef|grep postgres, you should see something like this:

[root@haddock ~]# ps -aef|grep 'postgres'
postgres  5963  5475  0 21:28 ?        00:00:00 /usr/postgresql/bin/postmaster -D <your postgres directory>
postgres  5972  5963  0 21:28 ?        00:00:00 postgres: writer process                          
postgres  5973  5963  0 21:28 ?        00:00:00 postgres: wal writer process                      
postgres  5974  5963  0 21:28 ?        00:00:00 postgres: autovacuum launcher process             
postgres  5975  5963  0 21:28 ?        00:00:00 postgres: stats collector process                 
admin     6750  6607  0 21:30 ttyS0    00:00:00 grep postgres
