->  Am just starting out with PostgreSQL and would like to learn more about
-> the spatial data handling ablilities of postgreSQL - in terms of using
-> R-tree indexes, user defined types, operators and functions. 
-> 
-> Would you be able to suggest where I could find some code and SQL to
-> look at to create these?
-
-Here's the setup for adding an operator '<@>' to give distance in
-statute miles between two points on the earth's surface. Coordinates
-are in degrees. Points are taken as (longitude, latitude) and not vice
-versa as longitude is closer to the intuitive idea of x-axis and
-latitude to y-axis.
-
-There's C source, Makefile for FreeBSD, and SQL for installing and
-testing the function.
-
-Let me know if anything looks fishy!
-
-A note on testing C extensions - it seems not enough to drop a function
-and re-create it - if I change a function, I have to stop and restart
-the backend for the new version to be seen. I guess it would be too
-messy to track which functions are added from a .so and do a dlclose
-when the last one is dropped.
