Based on the stack trace I was able to get it to break using simple
query:
select p.proname, (SELECT rolname from pg_catalog.pg_roles where oid = p.proowner) from pg_proc p;

I took a simple look at ranges of oid/prowner, and they look fine:

=# select min(proowner), max(proowner), count(*) from pg_proc;
min │ max │ count
─────┼─────┼───────
10 │ 10 │ 2970
(1 row)

16:38:34 db: postgres(at)postgres, pid:1991057
=# select min(oid), max(oid), count(*) from pg_roles;
min │ max │ count
─────┼───────────┼───────
10 │ 310235824 │ 244
(1 row)

Also, as I didn't mention it before: it's Pg 12.9.

Best regards,
