The article in the post above is a hack around this issue. If any other user installs your custom package (like any other package for Django) then it will fail with the same problem. Solve it correctly by mapping the correct migrations.

This looks like a migration dependancy order issue. You can control the order by ensuring that your custom migration file runs before the cms migration that adds PageUser. The following documentation describes this in detail:

Usually this will be enough, but from time to time you may need to ensure that your migration runs before other migrations. This is useful, for example, to make third-party apps’ migrations run after your AUTH_USER_MODEL replacement.
