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.

Is the payload decoded to utf8 when pg_enable_utf8 is true?

Best,
