The consumer is receiving a second :pg_snapshot_known message with a different xmin -- our function heads match either no xmin or an identical xmin.

This is happening during stack restarts so is perhaps due to processes dying and being restarted as part of that rather than the usual situation. Options are to either ignore this or accept the new value.
