postgis_geos_wrapper.cpp: GEOSGeometryType(Geometry *g1)
	returns malloced memory.

postgis_geos.c: GEOS2POSTGIS()
	calls GEOSGeometryType and never frees returned value.

I've seen many malloc calls in postgis_geos_wrapper,
would palloc be more appropriate there ?

Anyway - I'm not sure but I think that pfree'ing palloc'ed memory
in general might help in keeping memory usage under an acceptable
size. Don't know how postgres handles that exactly though ...
