I see that this has caused SELinux test failures on rhinoceros (the
ddl test fails). It looks like the output order is affected by the
implementation details of nbtree, likely for some system catalog
index. This is something that I've had to deal with in other places
(with a lot of help from Tom).

It's not easy for me to set up SELinux to fix the issue. Is there
somebody comfortable with that area that could confirm I have it
right, and provide me with the actual test output? Or push a fix
themselves?

Thanks
