As I understand it, PostgreSQL and SQLite3 drivers expect NULL to be the
last value in the the va_list args (for compatibility, I guess other
drivers should expect the same). This value should be placed there by
the caller. The drivers don't take into account any number figured out
in _prepare() as the number of values they should expect in
pvquery/pvselect. The behaviour of va_arg() shouldn't have anything to
do with this.
