Stabilize contrib/seg regression test.
If autovacuum comes along just after we fill table test_seg withsome data, it will update the stats to the point where we prefera plain indexscan over a bitmap scan, breaking the expectedoutput (as well as the point of the test case). To fix, justforce a bitmap scan to be chosen here.This has evidently been wrong since commitde1d042. It's notclear 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.
