Before we distribute more band-aids on this that might require manual
intervention, maybe we could step back and assess the situation to
make sure the issues are being comprehensively addressed, and perhaps
find a way to do it that is safe, idempotent, and requires no manual
intervention by users?

We have a lot of different types of users who might be affected by
this, and I worry that the pkgdb migration had already gotten out of
hand before we multiplied the cases that are out there with updates to
base and pullups to -8 and -9:

- netbsd-{8,9,HEAD} users using base pkg_install exclusively who have
  . base and pkgsrc
  . base
  . pkgsrc
  . neither

- netbsd-{8,9,HEAD} users using bootstrapped pkg_install exclusively
  who {have,haven't} updated pkgsrc

- netbsd-{8,9,HEAD} users using base pkg_install for main packages but
  bootstrapped pkg_install for /home/user/pkg or /usr/pbulk or
  similar, who have updated
  . base and pkgsrc
  . base
  . pkgsrc
  . neither

All these need to be multiplied by the different versions of the
manual intervention we've publicly suggested so far.  Did I miss any
important cases that we're likely to encounter?
