title: Getting PostgreSQL notifications into an AWS SQS Queue
body: <p>An application that I'm working on uses <code>AFTER CREATE/UPDATE/DELETE</code> triggers to create <code>pg_notify</code> notifications when certain actions occur within the system.  Currently, we have a small Node.JS application that <code>LISTEN</code>s for the events and then immediately turns around and posts them to an AWS SNS topic, which gets forwarded to our SQS event queue.  From that queue, we trigger all sorts of things based on the event (emails, SMSs, lambdas, long running jobs, etc).</p>
  
  <p>This architecture works well, but the Node.JS application that sits in between the PostgreSQL instance and the SNS topic seems a bit fragile.  I can't really run two copies in two availability zones, because messages will be duplicated.</p>
  
  <p>I'm looking for a better way to get these Postgres notifications into SQS.  Are there any options out there for this?  If Postgres Aurora has something, we <em>might</em> consider that.</p>
