In ClojureQL how can I make a where clause case insensitive?

In ClojureQL how can I make a where clause case insensitive? I am trying to add UPPER or something to do this in the where clause but开发者_如何学Go I can't figure out how to do this

---

In ClojureQL you can call a function like this:

:function/col

So something like this should work according to the documentation:

(select (table :users) (where (= :LOWER/name john)))
