Here is what I got from Stephen Frost on debian-openldap. His answer is
very interesting.

This is kind of odd..  It sounds like the slapd.preinst script was
unable to slapcat the database with the 2.0.27-4 slapcat- not a good
sign.  Once you move back to 2.0.27-4 you might shut down your database
and see what happens when you run slapcat on it, it *should* work but if
it doesn't it could definitely cause problems during upgrade.

The fix_ldif script is having a great deal of trouble performing the
migration from your old LDAP tree to a new compliant LDAP tree.  The
underlying problem is that the new version of slapd is much more picky
about schema's and proper form than the old version so we're trying to
fix old 2.0 LDIF's to be compliant.  Obviously this doesn't work in all

Unfortunately you may have to perform the conversion process yourself.
I'm willing to help and if we can fix things so that the conversion
process works for you that's great but it might not be possible to do in
a general way...

I expect the slapd database is, as you said, missing alot of things that
postfix is looking for which is what postfix is complaining about.

There's always http://snapshot.debian.net/
appears to have 2.0.27-4 packages).
