Ruby messes up when trying to do rake db:create with postgresql

Question

I have just installed postgresql, because I want to put my apps onto heroku. When trying to set up a new rails app using pq, once I rake db:create and I get the following error message, I have no clue what it means, or what to do.

Here's the error message that I'm receiving.

new-host-2:scheduleScraper rickmasta$ rake db:create:all
could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?

Answer 1

You may have installed postgres, but is it running?

I got almost identical errors after a reboot of my machine, because I didn't remember to (re)launch the postgres application locally. After I launched the PostGres application again, everything worked without a problem.

These were my errors:

    Is the server running on host "localhost" (::1) and accepting
    TCP/IP connections on port 5432?
could not connect to server: Connection refused
    Is the server running on host "localhost" (127.0.0.1) and accepting
    TCP/IP connections on port 5432?
could not connect to server: Connection refused
    Is the server running on host "localhost" (fe80::1) and accepting
    TCP/IP connections on port 5432?
    from /Users/gregorysmith/.rvm/gems/ruby-1.9.3-p429/gems/activerecord-3.2.13/lib/active_record/connection_adapters/postgresql_adapter.rb:1216:in `new'
etc, etc. ........

This is a known issue when installing PostgreSQL with brew on Mountain Lion. Postgres is putting the socket file in a different directory, /var/pgsql_socket_alt, then where psql, createdb, Rails, etc. know where to look for it. You need to change where the socket file goes via the postgres.conf file. See this link on how to fix it.
