It was the first time I've deployed Rails to EBS. And what a day of deployment it was…! The standard slew of production issues, using Amazon's relational database system for the first time, attempting (and failing) to dump/restore the old Heroku database:

pg_dump: 'dump' a database into a file.
pg_restore 'restore' a database from aforementioned dump.

At least, that's what I think was supposed to happen…
