Description
This feature request is to better support of third-party database backends.
In my case (Firebird SQL) to add a new field on already existing and populated table is not enough set and drop a default value, we need to update the new field with efective default value. It is not possible without commit the schema alteration.
An aproach could be to have a kind of hook to run sql statements (DML statement in this case) when the schema altereation finished (and commited). Of course, must bu runned in another transaction.
