NAME

    AnyMQ::Pg - Use built-in PostgreSQL 'LISTEN' and 'NOTIFY' commands for

    message-passing.

ABOUT

    Enables the use of PostgreSQL as a backend for message queueing

    functionality with AnyMQ.

    Many people are probably unaware that PostgreSQL has a built-in

    asynchronous publish/subscribe mechanism, but it does.

    

SYNOPSIS

        my $bus = AnyMQ->new_with_traits(

            traits     => ['Pg'],

            dsn        => 'dbname=postgres user=postgres',

            on_connect => sub { ... },

            on_error   => sub { ... },

        );

        # see AnyMQ docs for usage

        my $topic = $bus->topic('my_event');

        my $listen_watcher = $bus->new_listener($topic);

        $listen_watcher->poll(sub {

            my ($evt) = @_;

            warn "Got notified of my_event: " . Dumper($evt);

        });

        $topic->publish({ foo => 123 });

        AE::cv->recv;
