That's really strange ... it's not supposed to be possible to get that
error during xlog replay, because XLogOpenRelation is always willing to
create a file that doesn't exist.  Can you get a stack trace from the
crash dump this presumably left behind?

If you're just in a panic to get the DB up again, I'd try creating the
mentioned file ("touch $PGDATA/base/128873/129201") and see if it'll
start.  But if you have some time to investigate, it'd be good to try
to determine exactly what went wrong here.
