Funny, I just tested those yesterday. And they none of them seemed to work. And I think I had installed the newest version for the test. Anyways, I stand corrected. It's great to see some of these working now as the tab-completion is definitely better than psql's.
- \dn works
- \dm does not
- \dt <star>.users now appears to work as per psql
- \e works
- \i works
- \o does not
- \copy does not
