31826	AlterField with only db_column changed should be a noop	Iuri de Silvio	nobody	"When I change: `pink = models.Integer(default=0)` to `pink = models.Integer(default=0, db_column=""pink"")` the migration can recreate constraints if it is an FK or even reconstruct the table (SQLite).

The (same) constraint drop/create is a blocking operation for PostgreSQL, so it is an undesirable and unexpected behavior.
