Boxplot quantiles all at once

Editor's note: with a variety of supported statistical functions, including things like sampling and producing quantiles, DuckDB provides great analytical capabilities not always present in other databases.

Execute this SQL

select 
    unnest([.1,.25,.5,.75,.9]) as quantile,
    unnest(quantile_cont(i, [.1,.25,.5,.75,.9])) as value 
from range(101) t(i);

/* This returns:
| quantile | value |
|     0.10 |    10 |
|     0.25 |    25 |
|     0.50 |    50 |
|     0.75 |    75 |
|     0.90 |    90 |
