That's a good point, but the flip side is that, if we don't have such
a rule, a pg_dump of a hash-partitioned table on one architecture
might fail to restore on another architecture.  Today, I believe that,
while the actual database cluster is architecture-dependent, a pg_dump
is architecture-independent.  Is it OK to lose that property?
