How can I easily convert a Django app from mySQL to PostgreSQL?

Question

Has anyone done this? Is it an easy process? We\'re thinking of switching over for transactions and because mysql seems to be \"crapping out\" lately.

I wrote a Django management command that copies one database to another: https://gist.github.com/mturilin/1ed9763ab4aa98516a7d

You need to add both database in the settings and use this command:

./manage.py copy_db from_database to_database app1 app2 app3 --delete --ignore-errors

What cool about this command is that it recursively copy dependent objects. For example, if the model have 2 foreign keys and two Many-to-Many relationships, it will copy the other objects first to ensure you won't get foreign key violation error.
