+  names only a live assignee, its untargeted `ON CONFLICT DO NOTHING`, its

+  catalogue: the two set operations, the `RIGHT`, `FULL`, `USING`, `NATURAL`,
+  `CROSS`, comma, and `LATERAL` joins, a common table expression used as a
+  source, a `FROM` subquery, a multi-row `VALUES`, an `INSERT ... SELECT`, an

+  placeholder beside a subscripted column, and
+  `ReferenceServiceIntegrationTest.shouldCatalogueExactlyTheUnsupportedQueryFiles`
