Attached are two patches that each fix the issue -- a conservative
patch for v11, as well as a patch that actually propagates relmapper.c
state, for the master branch. It would be good to get a +1 on both
before pushing.

I'll pursue the parallel heap scan relfilenode cross-check thing
separately. Would still like to hear something from Robert on that
before proceeding.
