Re: function that resolves IP addresses

give this a try if you don't mind using plperlu.  This was tested with Postgresql 8.0.3


create or replace function gethostbyaddr(inet) returns text
as
$$
use strict;
use Socket;
my $inet = $_[0];
my $iaddr=inet_aton($inet);
my $name = gethostbyaddr($iaddr,AF_INET);
return $name;
$$
language plperlu;

select gethostbyaddr('199.181.132.250'::inet);
