that whenever you change MyProc->xmin, you always update TransactionXmin
too, so that TransactionXmin == MyProc->xmin is always true.
I committed a minimal fix in SnapshotResetXmin() only, in all stable
branches. I still think it might be a good idea to make it a strict
invariant tha
nd. What I was meant is that we make it a strict rule
that whenever you change MyProc->xmin, you always update TransactionXmin
too, so that TransactionXmin == MyProc->xmin is always true.

The comment in GetSnapshotData() defines transactionXmin like this:
TransactionXmin: the oldest xmin of any snapshot in use in the
current transaction (this is the same as MyProc->xmin).
However, we don't update TransactionXmin when we update MyProc->xmin in
SnapshotResetXmin(). So TransactionX
