Maybe not many use getaddrinfo()

If localhost isn't being resolved correctly are you seeing error 
messages like this on the server log (from pqcomm.c)?
  "could not translate host name \"%s\", service \"%s\" to address: %s"

Of course, using -i or -h "*" on the postmaster would inhibit that, but 
you would expect it in the default setup if localhost resolution fails.
