One thing I would say matters a lot still even if you use an ORM is PostgreSQL's support for transactional DDL. No more worrying about migrations crashing in the middle. You should of course still test your migrations but one less thing to worry about is always nice.

Interestingly the two db's I can think of that don't support transactional DDL are both Oracle products ;-)

Oracle has something that kind of looks like transactional DDL if you stand on your head and squint, but it doesn't cover, say, changes to table schemas.... it's only side by side versioning of stored procedures.....
