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

ejabberd: A scalable and robust instant messaging server. It is a distributed, fault-tolerant technology that allows the creation of large-scale instant messaging applications. The server can reliably support thousands of simultaneous users on a single node and has been designed to provide exceptional standards of fault tolerance; 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.

ejabberd and pg-amqp-bridge can be primarily classified as "Message Queue" tools.

ejabberd and pg-amqp-bridge are both open source tools. It seems that ejabberd with 4.18K GitHub stars and 1.25K forks on GitHub has more adoption than pg-amqp-bridge with 252 GitHub stars and 14 GitHub forks.
