Looks like attached patch solves an issue. It defines Row#dup not only
for 1.8, but for 1.9 too. Row#clone for 1.9 was defined just for "let
it be", I'm not sure that it's really required.
Output for the same SQLite3 file:
$ ruby1.9.1 testdbi.rb
Ruby version: 1.9.2
DBI driver: SQLite3
[[2, "moderator"], [22, "moderator"]]
It works.
