Wrong result with pgbench -C option?

Hi,

I ran pgbench with -C option. Here is an output.

% pgbench -C -c 10 -t 100 bench
starting vacuum...end.
transaction type: TPC-B (sort of)
scaling factor: 1
number of clients: 10
number of transactions per client: 100
number of transactions actually processed: 1000/1000
tps = 83.209663 (including connections establishing)
tps = 83.209663 (excluding connections establishing)

The first tps was equal to the second tps. I think it is wrong because
pgbench with -C option connects per transaction.

The attached patch calculates total connection time. Here is an output
with revised pgbench.

% ./pgbench -C -c 10 -t 100 bench
starting vacuum...end.
transaction type: TPC-B (sort of)
scaling factor: 1
number of clients: 10
number of transactions per client: 100
number of transactions actually processed: 1000/1000
tps = 108.410991 (including connections establishing)
tps = 228.657561 (excluding connections establishing)
