I assume you did not exit aptitude inbetween, right

So every package is listed under "New Packages"? I can't reproduce
this.

I just did the following inside an uptodate Stretch pbuilder chroot:

* Start "aptitude"

It shows this view:

-------------------------------------------------------------------------------
 Actions  Undo  Package  Resolver  Search  Options  Views  Help
C-T: Menu  ?: Help  q: Quit  u: Update  g: Preview/Download/Install/Remove Pkgs
aptitude 0.8.7 @ c6
--- Installed Packages (128)
--- Not Installed Packages (50663)
--- Virtual Packages (5897)


These packages are currently installed on your computer.                      ▒
                                                                              ▒
This group contains 128 packages.                                             ▒

* Press Ctrl-Z
* Edit /etc/apt/sources.list and change any occurrence of "stretch" to
  "buster".
* Called "fg" to get aptitude into the foreground again.
* Pressed "u" in aptitude's TUI.

Now aptitude shows me this view:

-------------------------------------------------------------------------------
 Actions  Undo  Package  Resolver  Search  Options  Views  Help
C-T: Menu  ?: Help  q: Quit  u: Update  g: Preview/Download/Install/Remove Pkgs
aptitude 0.8.7 @ c6

--- New Packages (13184)
--- Installed Packages (2)
--- Not Installed Packages (43508)
--- Obsolete and Locally Created Packages (15)
--- Virtual Packages (14460)

A newer version of these packages is available.                               ▒
                                                                              ▒

-------------------------------------------------------------------------------

Which is more or less what I would expect:

* 13184 new binary packages (You should get the same number on amd64
  unless you also have contrib/non-free or third-party repos enabled.)
* 111 of the 128 installed packages of the minimal chroot are updatable.
* 2 are unchanged between stretch and buster.
* 15 are no more in buster.

Maybe you can post even more verbose steps how to reproduce this.
Otherwise I have no idea what could be different with your setup to
cause such a different behaviour.
