I have gone ahead and rebased the refactor patch so it could cleanly
apply on heapam.c, see patch v7.
I am also attaching a patch (v8) that implements smgrimmedsyncrel() and
smgrimmedsyncseg() as I mentioned in the previous email. It avoids
callers to pass in InvalidSegmentNumber when they just want to sync the
whole relation. As a side effect, I was able to get rid of some extra
checkpointer.h includes.
