35589	AlterField should raise an error when changing primary key	Csirmaz Bendegúz		"At the moment, AlterField doesn't do anything if changing
`primary_key=False` -> `primary_key=True` or 
`primary_key=True` -> `primary_key=False`.

The same goes for `CompositePrimaryKey` fields (when/if they are merged #373).

Since changing the primary key is not supported by Django, AlterField should raise an error instead of silently failing."	New feature	closed	Migrations	dev	Normal	worksforme	primary key		Unreviewed	0	0	0	0	0	0
