I am not clear how this is an enhancement. The BKI file is a purely 
internal bootstrap mechanism, and I do not see any good reason to make 
pg_dump have any knowledge of it at all. pg_dump is already horribly 
complex (of necessity, to some extent, because it has to embody 
knowledge of previous releases). Anything that increases the complexity 
is to be avoided.

In any case, surely the whole point about upgrading would be to do it 
without bootstrapping a new location.
