Обсуждение: Apparently deprecated code in planner.c

Hi all,

I'm wondering whether the #ifdef FORCE_PARALLEL_MODE code [1] was deprecated:
    *    * FIXME: It's assumed that code further down will set parallelModeNeeded    * to true if a parallel path is
actuallychosen.  Since the core    * parallelism code isn't committed yet, this currently never happens.    */
 
#ifdef FORCE_PARALLEL_MODE   glob->parallelModeNeeded = glob->parallelModeOK;
#else   glob->parallelModeNeeded = false;
#endif

That comment is obsolete, but defining FORCE_PARALLEL_MODE is still a
useful thing to do for testing purposes.
