FWIW, the "fancy" here causes me to think about something likely to
cause syntax breakage of the query to be sent.

createuser -a 'user"1' -a 'user"2' 'user"3'
createuser -v "2023-1-1'; DROP TABLE public.x; select '" hoge

BUT, thses should be prevented by the functions enumerated above. So,
I don't think we need them.
