The analysis in the beginning of the discussion seems to be right, but 
the fix v2 looks too invasive for me.

Personally, I'd like not to remove snapshot even if transaction is 
read-only. I propose to consider "xid < TransactionXmin" as a legit case 
and just promote xid to TransactionXmin.

It's annoying this old bug still not fixed. What do you think?
