Hello, everyone!
Andres, added you in CC because I am referring to your words in
personal conversation.
Amit, I asked Andres about that situation and Andres said it is a bug
if we execute DirtySnapshot without holding a real one.
And this is how it is done in RelationFindReplTupleByIndex and
RelationFindReplTupleSeq now.
Best regards,
Mikhail.
