Hi Lance,

I can confirm both the regression and the fix. A pull request would be
great I think. I can also do it if you want.

Thanks,
Björn

The recent updates to set_user_disk_usage.py for Postgres users have
an issue with Postgres 8.x.  The SQL in the pgcalc method (line 51)
leads to the following error:

sqlalchemy.exc.ProgrammingError: (ProgrammingError) column "d.total_size" must appear in the GROUP BY clause or be used in an aggregate function
LINE 4: FROM (  SELECT d.total_siz...
            ^

The problem is that version of Postgres before 9.x were a bit more
restrictive in the use of GROUP BY.  This can be fixed using DISTINCT
ON instead.  See this StackOverflow post for more info:
http://stackoverflow.com/questions/1769361/postgresql-group-by-different-from-mysql

I've included a patch below.  Let me know if a pull request would be
preferred.
