[GENERAL] Function to return per-column counts?

hey,

Does anybody have a function lying around (preferably pl/pgsql) that
takes a table name and returns coverage counts?

e.g.

#> select * from column_counts('cats'::regclass);
column_name | all_count | present_count | null_count | coverage |
---------------------------------------
name | 300 | 100 | 200 | 0.66

Thanks!
