    pg_plan_advice: Handle non-repeatable TABLESAMPLE scans.
    
    When a tablesample routine says that it is not repeatable across
    scans, set_tablesample_rel_pathlist will (usually) materialize it,
    confusing pg_plan_advice's plan walker machinery. To fix, update that
    machinery to view such Material paths as essentially an extension of
    the underlying scan.
