I've also seen the reports of the same Assert(TransactionIdFollowsOrEquals(xid,
TransactionXmin)) with a subsequent crash in a parallel worker in
PostgreSQL v11-based build, Though I was unable to investigate deeper and
reproduce the issue. The details above in the thread make me think it is a
real and long-time-persistent error that is surely worth to be fixed.
