-- 0.20.0 (eighteenth review): a partitioned table, a partition and an inheritance tree are not watched. A key is
-- read in one table, under its own unique index; a partitioned table's index covers its partitions only when the key is
-- its partition key, and a read of an inheritance parent reads its children, which its index does not cover. Until the
-- seventeenth cut a partitioned table was watched (the sixth review fixed a partition whose columns stand in another
-- order); now watch() refuses it, and a read refuses a table that became one of these after watch() (truth_review18).
