Lion将rails连接到postgresql，使用ssd启动驱动器

Question

I'm trying to use postgresql with my rails development on Lion. My machine is currently set to boot from a solid state and store /home folder on a seperate hd. I'm able to create users for postgres fine using the

createuser

command

but when ever i try to create a db using rake

rake db:create

i get this error

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