My requirement is more than 15 thousand queries will run,
It will be 5000 updates and 5000 insert and rest will be select.

Each query will be executed in each psql client, (let say for 15000 queries
15000 thousand psql connections will be made).

Since the connections are more for me the performance is low, I have tested
it with pgbench tool.
