Hi everyone,  
I’m new in rails. After I ran “gem update --system”, I had a lot of  
problems when running rails projects. I tried to fix from error to error  
and now when I run rails project, it occurs error like this:

About your application’s environment  
PGError in Rails/infoController#properties

could not connect to server: No such file or directory  
Is the server running locally and accepting  
connections on Unix domain socket  
“/var/run/postgresql/.s.PGSQL.5432”?

Anyone who had had the same problem and solved it, please tell me how to  
do with this problem.  
Thank a lot
