​You should acquire an understanding of the difference between "host" and
"local" - only the former of which uses TCP/IP addresses and ports.

Once that is done the following will make a bit more sense:

http://www.postgresql.org/docs/9.2/static/libpq-connect.html#LIBPQ-CONNECT-HOST
host
Name of host to connect to. If this begins with a slash, it specifies
Unix-domain communication rather than TCP/IP communication; the value is
the name of the directory in which the socket file is stored. The default
behavior when host is not specified is to connect to a Unix-domain socket
in /tmp (or whatever socket directory was specified when PostgreSQL was
built). On machines without Unix-domain sockets, the default is to connect
to localhost.

Note especially the default behavior on the "Unix-domain" socket system -
which you are using.
