I fail to see how that gives him any answer on the views, and tables no
longer used. AFAICT, there's no way to know for views (apart from
logging all queries in the log). As for tables, still apart from the
log, pg_stat_user_tables could give an answer if he was monitoring it at
least the last six months.
