Hi Stephan
I am using Postgresql on MacOS X with gnu 3.1

I am using this for C++ builds
g++  -I/usr/local/pgsql/include -o testlibpq0 
-L/usr/local/pgsql/lib -lpq++
and for C build
gcc -I/usr/local/pgsql/include -o testlibpqc testlibpqc.c 
-L/usr/local/pgsql/lib -lpq

You sample is C++ or C prog ?
if is C prog are you include libpq-fe.h in you source code ?
PGconn is defined in this header.
