SQL:

 trace plan SELECT type, created_at, actor_login, action, number, repo_name FROM github_events WHERE LOWER(actor_login) = LOWER('NGAUT') ORDER BY created_at DESC LIMIT 1;

There is indeed a column-substitute from LOWER(actor_login) to _V$_index_ge_on_actor_login_lower_0 in logical rule &gcSubstituter{}

But we can't tell it from the dumped tracer file
