A very common use for asynchronous replicas is to offload long-running reporting jobs onto the replica so that they don't bog down the master. However, long-running reporting jobs often require temporary tables, especially if they use some 3rd-party vendor's reporting tool. For example, the average Microstrategy report involves between 1 and 12 temporary tables. -- Josh Berkus PostgreSQL Experts Inc. http://pgexperts.com
