Clarify resource utilization of parallel query.
temp_file_limit is a per-process limit, not a per-session limit across
all cooperating parallel processes; change wording accordingly, per a
suggestion from Tom Lane.
Also, document under max_parallel_workers_per_gather the fact that each
process involved in a parallel query may use as many resources as a
separate session. Caveat emptor.
Per a complaint from Peter Geoghegan.
