Perhaps, though of course it would need to be re-licensed.  I'd be
happy to see us pursue a snapshot cloning framework, wherever it comes
from.  I remain unconvinced that it should be made a hard requirement
for parallel pg_dump, but of course if we can get it implemented then
the point becomes moot.

Let's not let this fall on the floor.  Someone should pursue this,
whether it's Joachim or Koichi or someone else.
