It looks more like a bug in the general regression tests that are more likely
to be triggered by 027_stream_regress.

Depends on the patch, I think. It certainly also has triggered for bugs in
patches...

027_stream_regress.pl runs the normal regression tests via streaming rep - the
failure here is on the primary (i.e. doesn't involve recovery itself). Due to
the smaller shared_buffers setting the test uses, some edge cases are
triggered more often.
