We solved it (in our case) dropping the aggregate before upgrade and re-create in using new syntax in V14:

I hope it can help to improve pg_upgrade process.
The release notes say explicitly that one needs to drop and recreate the affected functions.

If you have an alternative solution to suggest that would help.
