Rails: rake db: create: all (failed to connect to server)

follow screencasts http://railscasts.com/episodes/342-migrating-to-postgresql?autoplay=true up to the steps "rake db: create: all" and get the error:

failed to connect to the server: such a file or directory is not a server running locally and accepts connections in the Unix socket domain "/tmp/.s.PGSQL.5432"?

refers to a Rails question : rake db: create: all cannot connect to a PostgreSQL database

but still cannot solve it. Not sure what the problem is. enter image description here
