No. It does have multiversion rows but rows updated in previous transaction
are not accessible to users.

The rows will remain on disk eating space till you vacuum. There is no way of
accessing them.

Actually it could be a nice feature if we could access them. For certain
applications, having entire database audited is like dream come true. Of
course it has to provide timestamps/transaction ids as well but in general
that would be pretty handy in some situation.

Alas... that is toooo much fundamental to ask for a feature..:-)
