mysql?

There's also an error in the document (which is not surprising, since  
the MySQL documentation on spatial is a little misleading, with most  
all of the OGC functions documented when only the constructors and  
accessors are actually fully implemented) which indicates that MySQL  
supports:

Buffer(g,d)
ConvexHull(g)
Difference(g1,g2)
Intersection(g1,g2)
SymDifference(g1,g2)
Union(g1,g2)

When it actually does not.
