I've added the table sizes and TPS in the performance results. As of
now, we've just performed stress testing using pgbench. We've plans
for performing other tests including:
1. Introduce random delay in the transactions instead of keeping a
transaction open for 15 minutes.
2. Combination of ROLLBACK and COMMIT (As suggested by Fabien)
3. PGbench tests for fixed number of transaction.
4. Modify the distribution (As suggested by Alexander Korotkov)

Do let me know if any other tests are required.
