on top of what Stephen said, I'd do as much preprocessing, and
preaggregation as possible to simplify and speed up those
report/analysis views....   for instance, storing min/max/mean rollups
per hour, per day, per month could mean the difference between a billion
row seq scan that takes hours and a few second query to graph a given
time range.
