[postgis-users] new GEOS goodies in PostGIS CVS

[Gregory S. Williamson]

FWIW, this naming convention follows Informix Spatial Blade, from which the DB2 stuff is derived. Not sure if the name is the important thing; 'tis the functionality. It does seems as if PostGIS/GEOS is approaching the spatial blade's functionality (although speed/performance issues may differ).

I just checked out DB2, all their spatial functions are prefixed with 
ST_.
ST_Union(), ST_Difference(), ST_Relate().
Sucks to have followed the namespace this far and to have to have a 
misnamed function at the end.  Apparently the SFSQL people weren't 
watching the SQL spec too closely when naming the functions.
