Be very carefull with using C++ functions inside postgresql.  If the C++ 
code throws an exception the postgresql backend will get a SIGABRT and 
terminate.

You can solve this by linking the std c++ library to the postmaster.  We 
tried everything we could think of to fix this, but this was the only 
solution that worked.

For a complete discussion, you can read the PostGIS (GIS spatial objects 
for Postgresql) mailing list (http://postgis.refractions.net) and the 
GEOS (Geometry Engine, Open Source) mailing list 
(http://geos.refractions.net).
