We required a "hot standby" server in order to get improved reliability. But we don't want it to sit there chewing power + money, unused. We want to *use* it to support our reporting applications. And the developers used temporary tables to marshal results used in some of those reports. There are conflicting senses of "read-only" here... - In one strict sense, to generate tuples in temp tables means it's not "read only" access. - But since the users running reports aren't allowed to modify the data in the application tables that they are querying, how is that *not* fairly characterized as "read only" access??? -- When confronted by a difficult problem, solve it by reducing it to the question, "How would the Lone Ranger handle this?"
