Based on my research and understanding of the Django migration issue, I can now provide the fix. The issue is in Django's migration autodetector where when a primary key field is renamed, the autodetector incorrectly generates an AlterField operation for ForeignKey fields that reference the renamed field, using the old field name in `to_field`.

The hint confirms this is a regression from commit `dcdd219ee1e062dc6189f382e0298e0adf5d5ddf`. The fix is to not generate the AlterField operation when the only change is the `to_field` pointing to a renamed field, since the RenameField operation already handles updating these references.

Here is the patch:
