With 0.0.9 of declare_schema I'm starting to fail if migrations cannot be run. At the moment this tends to be room for improvement on implementation vs limitations in Postgres.

Current limitations:

• Cannot modify table constraints, as of 17, only foreign keys can be anyway
• Cannot modify indexes. I'd like to improve this but it's also super messy. Index creation can take a while. I'm not sure how I'd like to handle this so the method at the moment is now to create a new index an later drop the old one.

I'm starting to get fairly confident in my usage of it. Going forward I hope to work more on docs and examples.
