thank you David.
I first run initialize step
$ pgbench -i -s 8000 sampledb
and then run step
$ pgbench -c 10 -j 2 -t 8000 sampledb
if I change -s/-t to lower value , eg, 100 above commands will show
--
set primary keys...
done.
done.
-- -
I am not getting it ,why it fails when I rise -t/-s to 8000 - with same commands.
Do you suggest that above is not correct way?

The primary keys are only created in -i mode, which can't be used in
conjunction with the options you've mentioned.
pgbench will perform a vacuum before an actual test run, so perhaps
that's what you're seeing. You may also have noticed it also didn't
perform the create tables and data population too without -i.
