The official terms are such that sockets in the file system namespace 
are AF_LOCAL (or AF_UNIX), and sockets in the Internet namespace are 
AF_INET.  So using "local (domain) socket" or "Unix (domain) socket" 
would be reasonable.  (Both are used by PostgreSQL.)  A pipe on the 
other hand is created by the pipe() function and does not have a socket 
or a namespace since it is internal to the creating process, which is 
the distinguishing characteristic between a pipe and a socket.
