This gem adds support for the postgres hstore type. It is the _just right_ alternative for storing hashes instead of using seralization or dynamic tables.

Make it easy to upsert on MySQL, PostgreSQL, and SQLite3. Transparently creates merge functions for MySQL and PostgreSQL; on SQLite3, uses INSERT OR IGNORE.

Flounder is the missing piece between the database and your Ruby code. It allows very simple access to database tables without going all the way to begin an object mapper.

Allows embedding documents in ActiveRecord models using PostgreSQL HStore
