I managed to break this test in two different ways in commit 05036a3155. First, the output of the new call to tuple_data_split() on the test sequence is dependent on endianness. This is fixed by setting a special start value for the test sequence that produces the same output regardless of the endianness of the machine. Second, on versions older than v15, the new test case fails under "force_parallel_mode = regress" with the following error: ERROR: cannot access temporary tables during a parallel operation This is because pageinspect's disk-accessing functions are incorrectly marked PARALLEL SAFE on versions older than v15 (see commit aeaaf520f4 for details). This one is fixed by changing the test sequence to be permanent. The only reason it was previously marked temporary was to avoid needing a DROP SEQUENCE command at the end of the test. Unlike some other tests in this file, the use of a permanent sequence here shouldn't result in any test instability like what was fixed by commit e2933a6e11.
