Perhaps it's just a wording thing, but I wouldn't use the term "replica"
when referring to something built with pg_dump/restore- that should
really be reserved for a slave system created through replication.

It certainly sounds interesting and I like the idea of it, but perhaps
we need a different mechanism than just passing in a raw snapshot, to
address the concerns that Tom raised.
