Save unnecessary round trips to the database

An ActiveRecord plugin providing a higher-level abstraction for SQL 'LIKE' queries

Gives ActiveRecord support for PostgreSQL's native inherited tables

From http://edgeguides.rubyonrails.org/active_record_migrations.html#types-of-schema-dumps: There is however a trade-off: db/schema.rb cannot express database specific items such as triggers, stored procedures or check constraints. While in a migration you can execute custom SQL statements, the schema dumper cannot reconstitute those statements from the database. If you are using features like this, then you should set the schema format to :sql. No longer is this the case. You can now use the default schema format (:ruby) and still preserve your check constraints.
