New pg_dump patch -- document statistics collector exception

This is a proposed patch to document disabling the statistics collector
pg_dump activity, and give a bit more visibility to the PGOPTIONS
environment variable supported by libpq.

It is an alternative to the prior patch, which supplied a --no-stats flag.

This is a documentation only patch, not tied to a recent code change.
