DBD::Pg has been ready since 2008, if you need something to test with. :)

Usage is:

while (my $notify = $dbh->pg_notifies) {
my ($name, $pid, $payload) = @$notify;
print qq{I received notice "$name" from PID $pid, payload was "$payload"\n};
}

Not sure what you mean by adapting interfaces to send payloads, I imagine
most if not all simply require a NOTIFY to be sent via PQexec.
