This might be of interest to HN readers in the New England area - once a year Tufte opens up his 200+ acre farm/sculpture park in western CT to the public for a day. I found out about this purely by accident this year, and it's a nice way to spend an afternoon. Google Tufte Hogpen Hill Farms for a sample of what he has there.

SCM solves the easy problem of maintaining the history of the DDL required to build an empty database from scratch (and you can even have DML under source control to populate the database with test data once it is built).

When version 1.2 of a table's DDL adds a new, not nullable column to the version 1.1 definition and there are a billion rows in production, you are looking at a one-off migration event.
