Thanks, the fix looks correct to me.

I spend some time rewriting all the comments; I found them pretty
difficult to read. Notable, they used many words to explain that a
transaction might not be marked as committed or aborted but we have
already checked that it is not running hence it cannot commit in the
future. While that's all true, I think it's still OK, and more
understandable to a human, to just call it an "aborted transaction", or
"aborted (or crashed) transaction" if you want to call out crashed
transactions separately. That's a concept that's explained in more
detail in existing comments in heapam_visibility.c.

See attached version with my comment changes.
