I don't see how this test will fail with force_parallel_mode=regress and max_parallel_degree > 0 even without the patch proposed to fix the issue in hand. In short, I don't think this test would have caught the issue, so I don't see much advantage in adding such a test. Even if we want to add such a test case, I think as proposed this will substantially increase the timing for "Select Into" test which might not be an acceptable test case addition especially for testing one corner case. > > Explain Analyze produces planning time and execution time even with TIMING OFF > so not adding the same to regress tests. > Yeah, that makes the addition of test for this functionality difficult. Robert, do you have any idea what kind of test would have caught this issue? With Regards, Amit Kapila. EnterpriseDB: http://www.enterprisedb.com
