If you're going to use a library, you'll have to link to it to get
a working program:

g++ -I/usr/include/pgsql myc.cpp -lpq++ -o myc

You may also have to link to the underlying C library, libpq:

g++ -I/usr/include/pgsql myc.cpp -lpq++ -lpq -o myc



And finally--shameless plug coming up--you may want to use libpqxx
instead of libpq++:
