@Gabrieli: Greetings! Hopefully what I'm working on will make Oracle support easier, too.
@Dries: Since it looks like db_num_rows() is going to be an issue for more than just PDO, would you be open to separate patches that just do "SQL cleanup" to eliminate db_num_rows(), clean up tablename-in-prepared-statement problems, etc, either as lots of little patches (my preference, easier to test/debug) or a big cleanup patch? I believe that will be the largest remaining part of PDO anyway, but valuable to native-Oracle efforts etc. as well.
