Specifies the directory of the Unix-domain socket on which the server is to listen for connections from client applications. The default is normally /tmp, but can be changed at build time. This parameter can only be set at server start.
In addition to the socket file itself, which is named .s.PGSQL.nnnn
where nnnn is the server's port number, an ordinary file named .s.PGSQL.nnnn.lock
will be created in the unix_socket_directory
directory. Neither file should ever be removed manually.
This parameter is irrelevant on Windows, which does not have Unix-domain sockets.
