The way we've solved other similar cases would translate like this:
instead of the "query for user names" just returning user names, add
on "UNION 'MAPPING FOR'". So if you do
# alter user <TAB>
where you're now offered
alice joe postgres
you'd instead get
alice joe postgres MAPPING FOR
Dunno if it's worth the trouble though.
