Why can't I find PGTuples() anywhere? What/where is it?
Anyway, I'm not sure I agree with TuplesAffected returning a 0 if
PQcmdTuples() returns NULL. An UPDATE can return 0 if it doesn't
update anything. It may be better to just wrap PQcmdTuples() in
pgdatabase.cc (since that's where PQntuples() is wrapped).
