One point here is that this confirms that the backpatched renaming alias
for PostgreSQL::Test::Cluster is working well.

Another is that, as far as I know, this is the going to be the only case
of any code being run under wal_consistency_checking=[not off]
regularly. 027_stream_regress.pl is equipped to do so, but as far as I
know we have no buildfarm animal with PG_EXTRA_TESTS set it so. I did
consider to make this new test conditional on having that flag be on,
but I disregarded it because of that.

A third point is that in branches 15+ I made it use pg_walinspect to
ensure that the desired WAL record is being emitted.
