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).
