Before and after analyze:

 

select schemaname,relid,indexrelid,relname,indexrelname from

pg_stat_all_indexes where relname='input_transaction_snbs';

 

schemaname |   relid   | indexrelid |        relname         |           indexrelname

------------+-----------+------------+------------------------+----------------------------------

snbs       | 535026046 |  616672654 | input_transaction_snbs | i1

snbs       | 535026046 |  616576519 | input_transaction_snbs | input_transaction_snbs_prod_pkey

(2 rows)

 

-------------------------------------------------------------------------------------------------------------------------------

 

SELECT idstat.schemaname AS schema_name,

       idstat.relname AS table_name,

       idstat.indexrelname AS index_name,

       idstat.idx_scan AS times_used,

       idstat.idx_scan AS times_used,

       pg_size_pretty(pg_relation_size(idstat.relid)) AS table_size,

       pg_relation_size(indexrelid) AS index_size,

       n_tup_upd + n_tup_ins + n_tup_del as num_writes

FROM pg_stat_user_indexes AS idstat

JOIN pg_indexes ON indexrelname = indexname

JOIN pg_stat_user_tables AS tabstat ON idstat.relid = tabstat.relid

WHERE idstat.relname = 'input_transaction_snbs'

AND indexdef !~* 'unique'

ORDER BY index_size desc;

 

schema_name |       table_name       | index_name | times_used | table_size | index_size | num_writes

Thanks. I was checking any INVALID indexes on the table. Its fine, can try below query. 

 

select schemaname,relid,indexrelid,relname,indexrelname from pg_stat_all_indexes where relname='i1';

 

Also, try to ANALYZE the database and retry the queries. Its just to confirm that query results are getting from updated catalogs.

Opps... correction in my query WHERE clause, it should be pointing to relname not index -- >where relname=' input_transaction_snbs'   <--
