History

Tom Lane d16ebfbff7 Stabilize contrib/seg regression test. If autovacuum comes along just after we fill table test_seg with some data, it will update the stats to the point where we prefer a plain indexscan over a bitmap scan, breaking the expected output (as well as the point of the test case). To fix, just force a bitmap scan to be chosen here. This has evidently been wrong since commit `de1d042f5`. It's not clear why we just recently saw any buildfarm failures due to it; but prairiedog has failed twice on this test in the past week. Hence, backpatch to v11 where this test case came in.	2021-06-07 14:52:42 -04:00
