You know that a local connection only works when you are logged in
on the database machine, right?

Is your database listening on port 5432?

Connect as user "postgres" and run the following queries:

   SHOW port;
   SHOW unix_socket_directories;

That will show the port and the directories where UNIX sockets are created.

You can use a socket directory name with the -h option of psql.
