[postgis-devel] Split By function

[Martin Davis]

This is one function which really needs a code example to show how to 
use it.  The description is very confusing to people (like me) who are 
unfamiliar with SRF's and UDT's (or whatever the set contains - 
presumably some kind of object?)

But clearly a very useful function.
