Right, but pg_getaddrinfo_all isn't getaddrinfo and doesn't claim to be. Since pg_getaddrinfo_all can return AF_UNIX as opposed to getaddrinfo, it's not clear why hints == NULL should mean ipv4|ipv6 here. Accepting NULL or also (subtly) breaks the API for pg_freeaddrinfo_all which is defined to take ai_family from the hints passed to pg_getaddrinfo_all. Now, reading the code makes it obvious that it will work anyways, but at the very least a patch to accept a NULL hint should update the function comment for pg_freeaddrinfo_all. -- Daniel Gustafsson
