Can we assume that by backup you mean pg_dump/pg_dumpall? If so, then
the change is likely due to increasing data in the database. I have a
daily report that emails me a crude but useful estimate of table
utilization based on this query:

The better way to do this would likely be to use the pg_*_size
functions detailed here:
http://www.postgresql.org/docs/8.3/static/functions-admin.html#FUNCTIONS-ADMIN-DBSIZE
In particular pg_total_relation_size() , |pg_size_pretty|(), and the
like... Seems much more straightforward than the queries mentioned
above..
You are, of course, correct. That is a better choice if you are up-to-date.
Unfortunately I still have some lingering servers that haven't been
upgraded to a version that includes that functionality (and I know I'm
not alone...) :)
Cheers,
Steve
