ok I now see why you (and I) failed to reproduce the problem - it only
causes clusters/databases to crash that were actually generated using
the upthread mentioned script. it does NOT fail using a dump generated
by a database that fails(!).
So the issue must be a bit more complex and somehow relate to some prior
stuff the script does.
