Steve,
Our system divides customers into distinct databases, however customers
are often clustered. (Think: different locations of 7/11) and so we have
to aggregate data from different databases. We do this with dblink to
get the data and temp tables to collate it, which appears to be a cause
of the bloat we're seeing.
