These tests provide coverage for RangeTblEntry and how query jumbling works with search_path, as well as the case where relations are re-created, generating a different query ID as the relation OID is used in the computation. A patch is under discussion to switch to a different approach based on the relation name, and there was no test coverage for this area, including how queries are currently grouped with search_path. This is useful to track how the situation changes between HEAD and any patches proposed. Christoph has proposed the test with ON COMMIT DROP temporary tables, and I have written the second part.
