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.

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "make all" and "make
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
