  A tool for automated migrations for PostgreSQL, SQLite and MySQL. (by tvallotton)

For Postgres and Mysql I only do a move if the user changed the type of a column. However, I'm not sure if this is absolutely necessary. I may revisit that, as I don't want to generate unnecessary moves. For Sqlite3, moves are necessary if the user wants to either delete a column, delete a constraint or add a constraint, as it doesn't support those statements. The program should create a table called temp, move all the rows to the new table, and then rename it. I'm not so proud of the code as it is right now though. I think it can still be a little clearer, but in line 203 of get_changes.rs you can see the point at which is determined if a move to a temporary table occurs.
