After restarting PostgreSQL, I can see the following parameters are set to
ON:
mydb=# show stats_start_collector;
stats_start_collector
-----------------------
on
(1 row)
mydb=# show stats_start_collector;
stats_start_collector
-----------------------
on
(1 row)
mydb=# show stats_block_level;
stats_block_level
-------------------
on
(1 row)
mydb=# show stats_reset_on_server_start;
stats_reset_on_server_start
-----------------------------
off
(1 row)
But still, if I query after performing heavy DML operations, I'm always
getting zero, even though there are INSERT/UPDATE/DELETE.
select pg_stat_get_tuples_inserted((select oid from pg_class where relname =
'mytable'));
Is there any other parameter I'm missing to make this work.

Yes, you're right. Maybe you have stats_start_collector at different
places in your postgresql.conf. The last value is used in this case. So
you should better check this.
