Hi,
How to change Gerserver's source code?
Can st_translate offset each point to different place? For example, I have a
shape which contains lots of points. Can st_translate offset each point to a
different place or just offset all points to a same place? I have spent more
than one week on looking for a solution. But I still cannot find it.
