So far best solution I can find is this. I’m sure there is a more elegant solution.
(conj
(d/q '[:find (pull ?e [*]) (pull ?e1 [*]) (pull ?e2 [*])
:where
[?e :customer/address-id ?address-id]
[?e1 :address/address-id ?address-id]
[?e2 :bank/address-id ?address-id]]
@conn)
(map #(conj % {:bank/name ""})
(d/q '[:find (pull ?e [*]) (pull ?e1 [*])
:where
[?e :customer/address-id ?address-id]
[?e1 :address/address-id ?address-id]
(not
[?e2 :bank/address-id ?address-id])]
@conn)))
