Indeed, now it seems to be always printed but the documentation did not 
follow, there should be a:
  latency average = 117.392 ms

In front of the tps line. Well, the performance displayed could also be 
improved... On my dual core SSD laptop I just got:
 sh> ./pgbench -c 10 -t 1000 starting vacuum...end. transaction type: <builtin: TPC-B (sort of)> scaling factor: 100
querymode: simple number of clients: 10 number of threads: 1 number of transactions per client: 1000 number of
transactionsactually processed: 10000/10000 latency average = 9.527 ms tps = 1049.665115 (including connections
establishing)tps = 1049.890194 (excluding connections establishing)
 

Which is about 10 times better.
