Its possible to do it directly, but its much easier to do using 
DirectFunctionCall2 because it handles all the details.  You have to 
remember that postgis function (in fact all postgresql VERSION1 
functions) are actually quite complex.  The details are in the function 
macros (ie. PG_FUNCTION_INFO_V1(...)).
