      > Hi Tatsuo,
      >
      > I've attached a patch for the version of pgbench in CVS. It includes the
      > following changes:
      >
      >     - fix some spelling mistakes, indentation stuff, etc.
      >
      >     - minor code cleanup -- (void) args instead of (), etc.
      >
      >     - allocate the state array dynamically, so that it is only as
      >     large as needed. This reduces the memory consumption of pgbench
      >     slightly, and makes a larger MAXCLIENTS setting possible
      >
      >     - (the only controversial change) add an option "-l" to log
      >     transaction latencies to a file. The "transaction latency"
      >     is the time between when the BEGIN is issued and the transaction
      >     commits. This is written to a file, along with the client #
      >     and the transaction #. The data in the file can then be used
      >     for things like:
      >
      >         - consistency analysis: is the TPS the same through the
      >         entire run of pgbench, or does it change?
      >
      >         - more detailed stats: what is the average latency, worse-case
      >         latency, best-case latency?
      >
      >         - graphs: feed the data to gnuplot, graph latency versus. time
      >
      >         - etc.
      >
      >     I was going to store this data in memory and write it to disk
      >     at the end of the pgbench run, but that isn't feasible because
      >     the data can be very large: for example, ~70MB if benchmarking
      >     128 clients doing 100,000 transactions each.
