Terracotta

This release contains **breaking** changes, which means that databases created with Terracotta v0.7.x are not compatible with v0.8.x.

To upgrade an existing database you can use the new command `terracotta migrate` (experimental):

bash
$ terracotta migrate mydb.sqlite


On a positive note, Terracotta now supports PostgreSQL as database flavor.
