For the record, Michael and I had a brief discussion about this
offlist and decided to abandon the idea of adding TAP tests, relying
only on buildfarm. Also I will check if we have a clear error message
in case when a user forgot to run pg_upgrade and running new slru.c
with old filenames. If the user doesn't get such an error message I
will see if it's possible to add it somewhere in slru.c without
introducing much performance overhead.

Also I'm going to submit precise steps to test this migration manually
for the reviewers convenience.
