If the instance is in addon-mode "all", then every zope-* package which
is installed will be added to the instance.

I suppose your first installed package was zope-psycopgda2 (and this is the
reason why the first traceback talks about ZPsycopgDA2), then you purged it
and installed zope-psycopgda (and this is the reason why the second
traceback is related to ZPsycopgDA).

At this point, everything is more clear to me: you are running a zope 2.8
instance which uses python2.3 but both python-psycopg and python-psycopg2
do not support python2.3 anymore. The reason for this choice is related to
the python policy (we'll support only python2.3 in etch) and obviously
there is no zope2.8 package in etch at the moment so the problem is
triggered by your old zope package.

Could you please confirm me the diagnosis? :)

I think the only reasonable thing to do is to drop support for zope2.7 and
zope2.8 from zope-psycopgda and zope-psycopgda2. In this way, it won't be
possible to install them in zope2.[78] instances (which is the right thing
according to the etch python policy).

Thanks,
