Previously I asked how to ALTER TABLE in Magento setup script without using SQL. There, Ivan gave an excellent answer which I still refer to even now.
However I have yet to discover how to use
Varien_Db_Ddl_Table::addColumn() to specify an
auto_increment column. I think it has something to do with an option called
identity but so far have had no luck.
Is this even possible or is that functionality incomplete?
