      - predefined variable "tps"
        The value of variable tps is taken from the scaling factor
        specified by -s option.
      
      - -D option
        Variable values can be defined by -D option.
      
      - \set command now allows arithmetic calculations.

      (Apologies for fat-fingering cvs commit command...) Should have read: · d156e1f8
      Tom Lane authored
      Remove unportable use of tfind/tsearch in favor of bsearch.  Fix up
      random number generator to use random() not rand() and to actually honor
      its min/max arguments properly.  That wasn't so important before, but
      with exposure of capability to ask for general ranges, it will be.

      The attached patch changes most of the usages of sprintf() to · 66eb8df6
      Bruce Momjian authored
      snprintf() in contrib/. I didn't touch the places where pointer
      arithmatic was being used, or other areas where the fix wasn't
      trivial. I would think that few, if any, of the usages of sprintf()
      were actually exploitable, but it's probably better to be paranoid...

      > 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.
