Well, it certainly could make sense to have different storage engines
for different access patterns. (Not for different degrees of
implementation correctness, mind you.) So let's just say we don't have
them.
Postgres was, however, one of the systems that in fact pioneered
pluggable storage managers. So we could say we're already one
generation ahead of everyone else: we had switchable storage managers,
realized we didn't need them, and got rid of them.
