pg_upgrade: document possible pg_hba.conf options Previously, pg_upgrade docs recommended using .pgpass if using MD5 authentication to avoid being prompted for a password.  Turns out pg_ctl never prompts for a password, so MD5 requires .pgpass --- document that. Also recommend 'peer' for authentication too. Backpatch back to 9.1.
