Enable parallel query by default

Enterprise / PostgreSQL - Robert Haas [postgresql.org] - 26 April 2016 07:35 UTC

Change max_parallel_degree default from 0 to 2. It is possible that this is not a good idea, or that we should go with 1 worker rather than 2, but we won't find out without trying it. Along the way, reword the documentation for max_parallel_degree a little bit to hopefully make it more clear.
