Currently we have a policy of doing a VACUUM FREEZE ANALYZE on a table
after a bulk load, or on the entire database after loading a pg_dump
of a database. We do this before putting the table or database into
production. This avoids surprising clusters of writes at
unpredictable times. Please don't defeat that. (I'm not sure whether
your current suggestion would.)
