If the cached plans are kept a bit longer than actually necessary, it
might also be possible to see the query plan of a query that involves
temporary tables, something that is somewhat convoluted to do
otherwise (ptop uses the query string from pg_stat_activity and tacks
an EXPLAIN in front of it, which breaks with temporary tables).
