pg-amqp-bridge vs WCF: What are the differences?

pg-amqp-bridge: Send Messages from PostgreSQL to RabbitMQ. This tool enables a decoupled architecture, think sending emails when a user signs up. Instead of having explicit code in your signup function that does the work (and slows down your response), you just have to worry about inserting the row into the database; WCF: A runtime and a set of APIs for building connected, service-oriented applications. It is a framework for building service-oriented applications. Using this, you can send data as asynchronous messages from one service endpoint to another. A service endpoint can be part of a continuously available service hosted by IIS, or it can be a service hosted in an application.

pg-amqp-bridge and WCF are primarily classified as "Message Queue" and "Realtime Backend / API" tools respectively.

pg-amqp-bridge is an open source tool with 251 GitHub stars and 14 GitHub forks. Here's a link to pg-amqp-bridge's open source repository on GitHub.
