Wow, great idea!

It's not immediately clear from the README, but is it easy to run with multiple profiles like "backwards-compatible", "revertable" (both data and schema) and "destructive" for that final clean-up in multi-staged no-downtime migrations? Basically common subsets of "safe-ness" of the schema migration queries.

I imagine it can be tuned, but I'd love this for all my projects.

And since I am currently on a project doing MS SQL (gasp), that'd be cool too ;)

I am familiar with an "is it a hot dog" app from back in the day, bit would have never made the connection :)
