Simple...

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???
