(with-connection db 
   (with-query-results rs ["select * from blogs"] 
     ; rs will be a sequence of maps,; one for each record in the result set. 
     (dorun (map #(println (:title %)) rs))))

(取自here)

为什么不尝试将rs更改为：

select point[0] as x,point[1] as y from table

这将工作吗？我不确定它会，但如果这种Clojure的查询方式只是将查询转发到DB“asis”，您可以尝试使用PostGIS操作符。
