I have this query I am executing against a postgres database instance 9.3,
<Code>
SELECT relname, seq_scan-idx_scan AS too_much_seq, case when seq_scan-idx_scan>0 THEN 'Missing Index?' ELSE 'OK' END, pg_relation_size(relname::regclass) AS rel_size, seq_scan, idx_scanFROM pg_stat_all_tablesWHERE schemaname='atg' AND pg_relation_size(relname::regclass)>80000 /*AND relname NOT IN ('iml_returns' ,'purch_order' , 'rpt_dates' ,'paypal_analysis_validation' , 'ntv_data_mv_cte' ,'sg_atg_test','sg_atg_set','personalized_skul', 'month_sku_rollup', 'on_order_sku_rollup', 'back_order_sku')*/
ORDER BY too_much_seq DESC;</Code>
This checks to see if there are more sequence scans than index scan.
When I execute the query it complains of the existing relations not being in existence with a SQL state:42P01.
