ERROR: relation “jobdeclinefeedback” does not exist
its because postgresql is case sensetive. On database Table name is “JobDecLineFeedback”
How can we fix your script about this issue.

I think this is the issue line:
pg_size_pretty(pg_relation_size(relname::regclass))

I find a quick adaption of this script better:

SELECT
relname AS TableName
,seq_scan AS TotalSeqScan
,CASE WHEN seq_scan> 0
THEN ‘Missing Index Found’
ELSE ‘Missing Index Not Found’
END AS MissingIndex
,pg_size_pretty(pg_relation_size(relname::regclass)) AS TableSize
,idx_scan AS TotalIndexScan
FROM pg_stat_all_tables
WHERE schemaname=’public’
AND pg_relation_size(relname::regclass)>100000
ORDER BY 2 DESC;

Here this solution was showing us many more tables with problems. Hope this helps someone!

Generally, you have to analyze filter, joins, table data and bases on that you should apply proper indexes.
