  1. Disable parallel query by default. 

    Change max_parallel_workers_per_gather default from 2 to 0.  When the
planner automatically chooses a parallel plan, the parallel query
infrastructure adds unpredictable overhead to a running postgres system.
This change prevents runaway parallel query execution in cases where
parallel plans are unknowingly chosen.
