In pg_upgrade, add various logging improvements: 

add ability to control permissions of created files
	have psql echo its queries for easier debugging
	output four separate log files, and delete them on success
	add -r/--retain option to keep log files after success
	make logs file append-only
	remove -g/-G/-l logging options
	sugggest tailing appropriate log file on failure
	enhance -v/--verbose behavior
