I appear to have a choice: 12.7 or 13.3. Which would be better for me to upgrade?
Those are PostgreSQL versions...but it's your non-psql client software that needs upgrading, not PostgreSQL.
Given that the messages above indicate you are presently running 12.2 you should be upgrading to the current minor release in the v12 branch regardless.
