Disable parallel query by default.

Browse Source 
Per discussion, set the default value of max_parallel_workers_per_gather
to 0 in 9.6 only.  We'll leave it enabled in master so that it gets
more testing and in the hope that it can be enable by default in v10.

<xref linkend="guc-max-worker-processes">. Note that the requested
number of workers may not actually be available at run time. If this
occurs, the plan will run with fewer workers than expected, which may
be inefficient. The default value is 2. Setting this value to 0
be inefficient. Setting this value to 0, which is the default,
disables parallel query execution.
