Thanks to Kathey, Shreyas, and Army for evaluating this bugfix.
1) I believe that Kathey's reservations are addressed by Suresh's response: This bugfix does not change any on-disk structures. It is OK for views to become invalid during downgrade.
2) I have added another comment to bug171, which I hope addresses Army's questions. I will purge from the submission the vacuously changed FromBaseTable. I will move my regression tests into the existing update.sql and delete.sql tests.
3) To answer Shreyas' question: Yes, this fixes bug 156 also. Cheers, -Rick
