I can't recall why I wrote that to filter out things in the pg_toast
namespace in the first place. I just took the easy way out here--the
query has been updated to not exclude relations in that namespace anymore
and I link to the TOAST docs for more details.
I consider combining all the values together, as you did in your example
code and as pg_total_relation_size does, as a different type of report.
Accordingly, I just updated with examples of both types, as well as
something to work against pre-8.1 databases.
