Hi,
pls tell me, I am currently running 2nd run in my box, (New attempt 2), and

The jar has an endless while loop. Thus please kill the PID when you are
done testing. It loosely follows the following:
BEGIN;
CREATE TABLE x (id BIGSERIAL PRIMARY KEY, payload1 VARCHAR, payload2
VARCHAR, payload3 VARCHAR, payload4 BIGINT, payload5 BIGINT);
/* Repeat until 2,000,000 rows are inserted */
INSERT INTO x (id, payload1, payload2, payload3, payload4, payload5) VALUES
(random values of varying length/size to force random toast usage);
COMMIT;
VACUUM (ANALYZE, FULL);
BEGIN;
/* Repeat until all 2,000,000 rows are updated */
UPDATE x SET payload1 = , payload2 = , payload3 = , payload4 = , payload5 =
... again random values of varying length/size to force random toast usage
COMMIT;
VACCUM (ANALYZE, FULL);
If the error is going to occur it will happen during the second "Attempting
vacuum" phase.
1st vacuum:
c.setAutoCommit(true);
System.out.println("Attempting vacuum");
c.prepareCall("VACUUM (FULL, ANALYZE, VERBOSE) x").execute();
System.out.println("Vacuum end. 30 sec sleep");
Thread.sleep(60000);
2nd vacuum:
System.out.println("Attempting vacuum");
c.prepareCall("VACUUM (FULL, ANALYZE, VERBOSE) x").execute();
System.out.println("Vacuum completed");
Thread.sleep(30000);
System.out.println("Dropping the table");
c.createStatement().execute("drop table if exists x");
Thread.sleep(30000);
Hope this helps!
Best wishes,
Harry
