Hi , 

I just have a quick question , I am developing a gps/gis application at
the moment and I am using postgresql as my database with postgis as a
spatial extension. 
I was wondering is it possible to calculate the distance between an
external point and a polygon . I am using lat/lon as units . The error I
am receiving is
