No way to call cancel() on query about pg-promise

[vitaly-t]

Cancelling queries isn't a frequent feature to be used by developers, for sure. In fact, you are the first one to ever ask about it.

I personally have never used it. And now that you have asked, I just had a quick look at its implementation in file index.js

// cancel the query runned by the given client
PG.prototype.cancel = function(config, client, query) {
  if(client.native) {
    return client.cancel(query);
  }
  var c = config;
  //allow for no config to be passed
  if(typeof c === 'function') {
    c = defaults;
  }
  var cancellingClient = new this.Client(c);
  cancellingClient.cancel(client, query);
};

I'm not sure how this function really works underneath - is it synchronous or asynchronous? If it is the latter, then what even does it provide? It would be interesting to find out.

In the meantime, you can access the pg instance via pgp.pg property, and call pgp.pg.cancel() the way you used to, I just don't know yet how it will work in this case. I think it was initially designed for use with the native client only, and since this library relies on connections from the pool,...

Try and see if it works, and let us know ;)
