The below references are already properly documented in
https://www.postgresql.org/docs/current/catalog-pg-event-trigger.html
but missing in src/tools/findoidjoins/README.
Join pg_catalog.pg_event_trigger.evtowner => pg_catalog.pg_authid.oid
Join pg_catalog.pg_event_trigger.evtfoid => pg_catalog.pg_proc.oid
I'm not sure what the process of updating the README is,
the git log seems to indicate this is usually part of the release cycle,
so perhaps it's OK this file is out-of-sync between releases?
But if so, that won't explain these two, since they have been around for ages.
