This test case involves partitioning, but also pruning, which is very
particular about heap tuple headers being a certain way following
updates. I wonder if we're missing a
HeapTupleHeaderIndicatesMovedPartitions() test somewhere. Could be in
heapam/VACUUM/pruning code, or could be somewhere else.
Take a look at commit f16241bef7 to get some idea of what I mean.
