LISTEN query timeout with node-postgres?

Question

I have an \"article\" table on a Postgresql 9.1 database and a trigger that notifies a channel on each insert.

I\'d like to create a node.js script that catches those in

Answer 1

I got answer to my issue on the node-postgres repo. To quote Brianc:

pg.connect is use to create pooled connections. Using a connection pool connection for listen events really isn't supported or a good idea though. [...] To 'listen' a connection by definition must stay open permanently. For a connection to stay open permanently it can never be returned to the connection pool.

The correct way to listen in this case is to use a standalone client:

var pg = require ('pg'),
    pgConnectionString = "postgres://user:pass@localhost/db";

var client = new pg.Client(pgConnectionString);
client.connect();
client.query('LISTEN "article_watcher"');
client.on('notification', function(data) {
    console.log(data.payload);
});
