[Zope] Re. Zope for a article publication site

PosgreSQL has a native "text" data type that can grow to a large size transparently. Accessing records of this type should be very effective as a means of publishing raw text, formatted via DTML. It should be fairly easy to store huge volumes of text in PostgrSQL while the size of the Zope ODBMS remains much smaller, since it only needs to store the presentation pieces. I don't know enough about ZCatalog yet to say whether you could successfully integrate the two, but perhaps some of the other interesting native features of PostgreSQL could stand in, since indexing is what DMSs do best.
