Michael,
Following is the output of Vacuum analze on the same table:
psql =# VACUUM ANALYZE verbose cam_attr;
INFO: vacuuming "public.cam_attr"

VACUUM
Also how do we check if the statistics are set to Zero for the table?

Is there any data in the table? What does ANALYZE VERBOSE or VACUUM
ANALYZE VERBOSE show for this table? Is there any chance that
somebody set all of the columns' statistics targets to zero?
