/*
  *      pg_getnameinfo_all - get name info for Unix, IPv4 and IPv6 sockets
  *
  * The API of this routine differs from the standard getnameinfo()
definition
  * in two ways: first, the addr parameter is declared as sockaddr_storage
  * rather than struct sockaddr, and second, the node and service fields are
  * guaranteed to be filled with something even on failure return.
