Re: [HACKERS] Listen/Notify payload and interfaces
-BEGIN PGP SIGNED MESSAGE-
Hash: RIPEMD160
With the new listen/notify implementation we can send a payload along
with the notification. This has been in the protocol already since
years and there is no change needed for libpq. However we need to
adapt the various interfaces to allow a payload to be sent and
received.
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?
