I got the follwing error: >> Could not load library "$libdir/pg_upgrade_support" Hmm, pg_upgrade_support isn't a separate library anymore; it's been merged into core. I would not have expected that to cause any problems, because the functions in that library shouldn't have been referenced in your old database in the first place. They were supposed to be installed and then removed again during the process of (prior versions of) pg_upgrade. I'm guessing you had leftovers from old failed pg_upgrade attempts that you never completed. What you want to do is simply manually drop the functions referencing $libdir/pg_upgrade_support. A look into the pg_upgrade sources suggests that this ought to do it: DROP SCHEMA IF EXISTS binary_upgrade CASCADE; though you'll probably have to do that in every database of the installation. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
