I am coming very late to this discussion, but I do have some
information. Basically, pg_upgrade is trying to predict if the
dump/restore will fail by checking references to shared objects in the
old cluster. It sees a reference to json_build in the old cluster and
assumes this is needed in the new cluster, when in fact it isn't.
We could have hard-coded this knowledge into 9.4 pg_upgrade if we had
known it. The simple solution is to install json_build94 as you did,
run pg_upgrade, then just uninstall json_build94 as nothing depends on
it. Not sure if this should be in the pg_upgrade docs or not.
