TODO item inquiry/claim

Hi all,
 In looking over the TODO doc, I saw

* Add table name mapping for numeric file names
 After reading the thread that bore that entry, I'd like to 
submit a bit of code for consideration, since it solves at least one 
of the problems raised in that thread.  You may fetch it from cvs;sh$ cvs -d :pserver:anoncvs@rcfile.org:/var/cvs login
 [no password, just press enter]sh$ cvs -d :pserver:anoncvs@rcfile.org:/var/cvs co pg_stat_dush$ echo "read the
README"

It's been tested with 7.1 and 7.2bN and is basically a few c functions
that allow (approximate) reports of disk usage (in Kb) per database, 
and  per relation (only on the current database, for now).

brent=# SELECT datname, pg_du_db(datname) AS diskusage FROM pg_database; datname  | diskusage 
-----------+-----------brent     |      1785template1 |      1713template0 |      1713
(3 rows)

brent=# select relname,pg_du_rel(relname) as diskusage from pg_class        
brent-# where (relkind='r' or relkind='i') order by diskusage desc;            relname             | diskusage 
---------------------------------+-----------pg_proc                         |       252pg_proc_proname_narg_type_index
|      236pg_description                  |       100pg_attribute                    |        92pg_operator
       |        84
 
...

 If you guys could suggest what needs to be added/modified to allow
Bruce to mark off that TODO item, I can probably get that done later
today.

cheers. brent
