Hi Laurenz Albe,

Thanks for your response.

But file   ".s.PGSQL.5432" does not exist .
How can I re-create this or any other option?

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.
