Actually, I was trying to distinguish it from all-visible because I
interpret that to mean every thing is visible -- as in, every tuple on
a page is visible to everyone. And here we are referring to one xid
and want to know if it is visible to everyone as no longer running. I
don't think my name ("visible-to-all") is good, but I'm hesitant to
co-opt "all-visible" here.
