I wrote the regression test that causes Postgres to crash with the
patch applied. It tests, among other things, that CLUSTER tuples are
fixed-up by a routine like the current MOVETUP(), which is removed in
Heikki's patch. (There was a 9.6 bug where CLUSTER was broken due to
that.)
It shouldn't be too difficult for Heikki to fix this.
