I did not use configure - I downloaded a set of RPMs for 6.5.3
I then just changed the program not to require PgEnv and then compiled,linked with
the libpq++ library.
Maybe I should download the sources and compile on my system, but I dont see how
that will change what I see as momory not being released in the PgDatabase
destructor.
