unnest-like pg_stats.most_common_values and pg_stats.most_common_freqs

Hi all,
maybe this is trivial, but I need an hint on a way to see a table form
of the MCVs and MCFs out of pg_stats with a query. Is it possible to
get a set of rows each with a most common value on one column and the
corresponding column on the the other? (assuming I can cast the array
of MCVs to the right type array)

Thanks,
Luca
