Continuous aggregates on continuous aggregates

You can create a continuous aggregate on top of another continuous aggregate. This allows you to summarize data at different granularity. For example, you might have a raw hypertable that contains second-by-second data. Create a continuous aggregate on the hypertable to calculate hourly data. To calculate daily data, create a continuous aggregate on top of your hourly continuous aggregate.
