Below is some source code snippet I thought can help you.

src/interfaces/libpq/fe-connect.c
777 #ifdef HAVE_UNIX_SOCKETS
778         /* pghostaddr and pghost are NULL, so use Unix domain socket */
779         node = NULL;
780         hint.ai_family = AF_UNIX;
781         UNIXSOCK_PATH(portstr, portnum, conn->pgunixsocket);
782 #else

src/include/libpq/pqcomm.h
77 /* Configure the UNIX socket location for the well known port. */
78 
79 #define UNIXSOCK_PATH(path,port,defpath) \
80         snprintf(path, sizeof(path), "%s/.s.PGSQL.%d", \
81                 ((defpath) && *(defpath) != '\0') ? (defpath) : \
82                 DEFAULT_PGSOCKET_DIR, \
83                 (port))
