Removing it is a little premature. :) Definitely going to add a warning 
about relying on its output, though. The query itself was created and 
integrated into the check_postgres.pl nagios plugin as a very, very 
gross estimate of bloated tables.

It wasn't the most accurate thing in the world, but considering what it 
had to work with, it did a pretty good job. Generally CLUSTER or VACUUM 
FULL would remove a table from the query output, but not always. It's 
those edge cases that cause problems.
