If you're on a version of pgsql with generate_series, you can use that
to easily create a pivoting data set on the fly to do this.
If you're on an older version, it's easy enough to make a generic pivot
table and keep it around to do these things. Since we're still on 7.4
where I work, we use the pre-populated pivot table. It's primitive, but
it works.
