You'll find the diff in the "artifacts", but not a separate "diff" file.
https://api.cirrus-ci.com/v1/artifact/task/6146418377752576/testrun/build/testrun/pg_upgrade/002_pg_upgrade/log/regress_log_002_pg_upgrade

CREATE FUNCTION public.regress_psql_df_sql() RETURNS void
LANGUAGE sql
BEGIN ATOMIC
- SELECT NULL::text;
+ SELECT NULL::text AS text;
END;

It's failing because after restoring the function, the column is named
"text" - maybe it's a bug.

Tom's earlier point was that neither the function nor its owner needs to
be preserved (as is done to exercise pg_dump/restore/upgrade - surely
functions are already tested). Dropping it when you're done running \df
will avoid any possible issue with pg_upgrade.

Were you able to test with your own github account ?
