> Adding SUMMARY statement to HPL/SQL to describe a data set (table, query result) similar
to Python and R.
> For each column output the data type, number of distinct values, non-NULL rows, mean,
std, percentiles, min, max. Output additional stats for categorical columns. This helps perform
quick and easy exploratory data analysis for SQL devs and business users.  http://hplsql.org/summary
