Adding Postgres Inbound Connector

[superbeagle]

Hello, Team!

I am Joe Pappas from Camunda. We are happy to introduce our Inbound connector and think it will contribute to the community.

About the Connector

The Inbound Connector takes advantage of the 'channel' feature of Postgres. Changes to a Postgres database can be sent to a Postgres channel where external applications (like the Inbound Connector) can subscribe and act upon those messages
