30896	"""OperationalError: (1054, ""Unknown column ...)"" error when running migrations on an empty MySQL database."	coolnodje	nobody	"I keep hitting this problem while trying to replay an entire database migrations on a new fresh DB (from MySQL to PostgreSQL to be precise).

MySQL complains of a non existing column that was removed in a later stage of migrations.
This column doesn't exist in MySQL anymore as it is up to date with the newest migration. So it's only natural that the column cannot be found.

The question is: why is `migrate` looking for this column at this stage? It can only be found in the target new DB.

I'm not including any code at this stage but I guess I can probably find a way to share the whole migrations if this doesn't sound like an already addressed problem."	Bug	closed	Migrations	dev	Normal	needsinfo			Unreviewed	0	0	0	0	0	0
