Postgres permission denied on MAC OS X

Question

I was following the ruby on rails tutorial to run with postgres but when I try the "rake db:create" I get the following error:

could not connect to server: Permission denied
    Is the server running locally and accepting
    connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?

I have found this question issuing some similar problem but I couldnt make it work anyway.

Repairing Postgresql after upgrading to OSX 10.7 Lion

I have installed homebrew after reading this question and the path is fine, brew doctor shows me no errors on path.

Answer 1

Instead of troubleshooting your socket file permissions, you could try a TCP connection. Add host: localhost to your config/database.yml. Of course, this will only work if postgres is listening for TCP traffic. Postgres listens on port 5432 by default, so netstat -an | grep 5432 will tell you if it is listening.
