Is there a messaging system for Postresql

["Romeliz Valenciano Jr." <jedi_knyt23@xxxxxxxxx>]

Hi,

We're evaluating Postgresql for a possible transition from MS SqlServer. We have 100s of MS Sql servers and one way of replicating data changes is to use MQ Series Queue management system, some servers who were recently changed to Sql 2005 are using Service Broker. We're interested if there's an existing messaging system/tool present in Postgresql as well.

Thanks
