So do the schemas exist in the 9.0.3 database?
As you stated there are dependency issues but I have not seen that be a problem. 
The error messages you saw are not unusual and are probably more of the 
informative kind, not the fatal kind. I don't suppose you had logging turned on 
in the 9.0.3 server when you did the restore?

There some parts of the server start that may not make it into the logs but most 
does, so yes they would be useful.

Have you looked in postgresql.conf or pg_hba.conf to see if the above is there?
