I'd imagine you cannot have the extension pre-created in the new cluster
before the upgrade proceeds. Especially if it's a newer version. You may
have to do the upgrade with the old version of the extension installed and
then update to the new version after the PG upgrade.

If you don't get any further responses on this list, it may be better to
try and contact Citus for further support or make an issue on their github
