[pacman-dev] 'replaces' confusion

Let us go back to days of yor.  Once upon a time, pacman's db format
looked different than it does today.

[jchu at wingnut pacman-2.9.8-4]$
cat /var/lib/pacman/local/pacman-2.9.8-4/install

...
post_upgrade() {
  if [ ! -d var/lib/pacman/local ]; then
    echo "==> Converting database..." >&2
    mkdir -p var/lib/pacman/local && usr/bin/convertdb
var/lib/pacman/local echo "==> Done." >&2
  fi
...

Not trying to argue for changing the db format now, just mentioning
that it's been done before and the references still exist.

As nice as it sounds, I think top priority is getting 3.0 out.  I vote
to not delay it.
