Sorry to be a pedant, but Atomic != Transactional.

Transactions require the ability to maintain all 4 ACID semantics
even if you pull the power plug in the middle, and even if someone
else is updating an overlapping set of objects. MyISAM is *not*
transactional, for example.

A proper relational database will give you transactions, and PStore won't.
If that matters to you :-).
