Actually, I think anyone using postgis-specific things should use
the version with no ST_ prefix. When you use ST_ it's because you're
hoping your code will "just work" with any ISO-compliant thingy.

If you're using rasters, and they are not ISO-standard, you should
use Intersect() for both rasters and vectors. You know you're talking
to postgis and not a generic ISO standard SF dbms.
