Ah, I should have explained better. I meant how much of a column is
null.
Basically you have to
0. count how many total records in a table
1. discover the column names in a table
2. for each column name, count how many nulls and subtract from total
count
If nobody has one written, I'll write one and blog it.
Thanks!

PS. In a similar vein, we published
http://blog.faraday.io/how-to-do-histograms-in-postgresql/ which gives
plpsql so you can do:
SELECT * FROM histogram($table_name_or_subquery, $column_name)
