Having trouble with Postgres since I upgraded to Mountain Lion (and now regretting it). Lost hours trying to fix it to no avail.
rails server then visiting my app at 0.0.0.0:3000 I get this error.
psql: 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"?
tried updating xcode.
