Creating and deleting tables can result in unusable tables #2224

In, performing table creates and deletes concurrently (or perhaps just in rapid succession) can render a table completely unusable; perhaps indefinitely. Inserts fail because of constraint violations (even though every column has a default set!), reads fail because the table doesn't exist, create if not exists apparently succeeds, but the table can't be deleted, because it's already being deleted.


2019-09-05 14:42:44,392{GMT}    INFO    [jepsen worker 3] jepsen.util: 11048    :info    :drop-table    nil    [:psql-exception "ERROR: Not found: The object was deleted: Started deleting at 2019-09-05 18:38:29 UTC"]


INFO [2019-09-05 14:40:02,017] jepsen worker 0 - jepsen.util 3475    :info    :read    nil    [:psql-exception "ERROR: Not found: Error loading table with oid 16386 in database with oid 12453: The table '' does not exist"]


INFO [2019-09-05 14:41:22,649] jepsen worker 4 - jepsen.util 7579    :info    :insert    nil    [:psql-exception "ERROR: null value in column \"k\" violates not-null constraint\n  Detail: Failing row contains (null, null)."]

You can reproduce this with Jepsen 60d3417: see the default-values test.

lein run test --os debian --version -w ysql/default-value --time-limit 300
