を使用してJDBC /クエリ私はコルマを使用して簡単なアプリケーションを作成しようとしています：間違った数は（4）に渡さ：コルマ
(ns some-proj.core)
(use 'korma.db)
(defdb db (postgres { :host "localhost"
:port 5430
:db "mydb"
:user "myuser"
:password "mypass"
}))
(use 'korma.core)
(defentity tags
(database db))
(defn foo []
(println (select tags)))
をしかし、私はエラーを取得する：
PS D:\dev_experiments\some-proj> lein run
