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' <--
