It's hardly that important, but we (Postgres Pro) run this test
regularly to check for primary-standby compatibility. It's useful when
checking binary packages from different minor versions. For example, we
setup postgresql-14.0 and postgresql-14.1 aside (renaming one
installation' directory and changing it's port) and perform the test.
What've found with it was e.g. incompatibility due to linkage of
different libicu versions (that was PgPro-only issue). I don't remember
whether we found something related to PostgreSQL itself, but we
definitely use this test and I'm not sure how to replace it in our setup
with a TAP test. On the other hand, testing binaries is not accustomed
in the community yet, so when such testing will be adopted, probably a
brand new set of tests should emerge.
Best regards,
Alexander
