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' <--
