A compromise that occurred to me after a bit of reflection is to place
the necessary table-drop commands in a new regression test script that's
meant to be executed last, but isn't actually run by default. Then
teach the cross-version-update test script to include that script via
EXTRA_TESTS. Manual testing could do likewise. Then we have a small
amount of pain for testing upgrades, but we lose no test coverage in
back branches.
