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.)
