support "after col_name" in add_column

[anonymous]

After applying an add_column migration, I noticed the new columns were appended to the end of the table columns. This surprised me, because I had modified my models.py by adding fields in specific positions, and I assumed South would use that ordering. Now my table and my Model class are out of synch (with respect to field order). Could a flag be added to support this correspondence?

I suppose it could be done, but it's not supported on all backends, and column ordering is considered a non-essential database feature in South, so I'm marking this as [sometime in] The Future.

+1'ing this feature. I know it's not an essential db feature, but for readability (when using SQL Pro for instance), it's great.
