psycopg2 is a python binding for postgres, not a ZOPE product. Therefore the subpackage ZPsycopgDA is necessary. It is included in the psycopg2 source package. The best way to install is to add psycopg2 as egg to your buildout and copy ZPsycopgDA to your Products folder.
On this side I want to remind on #29 that would make it easy to install psycopg2 and ZPsycopgDA in a Plone buildout.
By the way, Plone/zope2/lib/python/Products folder was never a good place to add Add'ons. Neighter in buildout based installs nor in old fashined zope installs.
