all right got refresh token exchange working too. i had to extend some protocol to translate org.postgresql.jdbc.PgArray to #clojure vectors but it works now
@valerauko @yogthos
I would be lost without the Luminus documentation and _Web Development with Clojure_.
as usual based on @yogthos's luminus guide
```
(extend-protocol jdbc/IResultSetReadColumn
org.postgresql.jdbc.PgArray
(result-set-read-column [value metadata index]
(vec (.getArray value))))
```
