I followed an instruction on how to setup Ubuntu 10.04 with PostgresSQL
$ psql
Or this:
lucid@ubuntu:~$ sudo -u postgres psql postgres
[sudo] password for lucid:
psql: 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 knows a solution?
