In C, you'd probably want to use
const char *OldLocale = setlocale(LC_NUMERIC, "C");
Then run the pointer returned by PQgetValue() through atol() to get a
numeric value, and finally restore the previous locale with
setlocale(LC_NUMERIC, OldLocale);
If you're using C++, best thing to do may be to use libpqxx instead of
libpq. It has functions to do the conversions for you, and takes care of
locale and overflow issues as well.
