You can easily do that with PLperl
The funtion then connects to the server running on localhost, and sends
some commands terminated with CRLF.
CREATE or REPLACE FUNCTION public.psendpopup(text,text)
RETURNS pg_catalog.varchar AS
$BODY$
use IO::Socket;
$sock = new IO::Socket::INET (
PeerAddr => 'localhost',
PeerPort => '32000',
Proto => 'tcp',
);
die "Could not create socket: $!\n" unless $sock;
print $sock "null\r\n";
print $sock "send_broadcast\r\n";
print $sock $_[0]."\r\n";
print $sock $_[1]."\r\n";
close($sock);
$BODY$
LANGUAGE 'plperlu' VOLATILE;
