Michael,
Following is the output of Vacuum analze on the same table:
psql =# VACUUM ANALYZE verbose cam_attr;
INFO: vacuuming "public.cam_attr"
INFO: index "cam_attr_pk" now contains 11829 row versions in 63 pages

INFO: "cam_attr": scanned 103 of 103 pages, containing 11829 live rows and 0 dead rows; 6000 rows in sample, 11829 estimated total rows
VACUUM
Also how do we check if the statistics are set to Zero for the table?

Nimesh.

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?
