Subject: [PATCH] Add Patronis default postgres configs to the sample yml files
 (#1909)

This adds the default Postgres settings enforced by Patroni to the `postgres{n}.yml` files provided in the repo. The documentation does call out the defaults that Patroni will set, but it can be missed if you download postgres0.yml and use that as a starting point. Hopefully the extra commented out configs serve as a visual cue to save the next person from the same mistake :)
